Sorry for my bad English.
Okay, let's go: when I try to validate my form using jQuery, it works just the else option.
I'm considering a spacing in between names, for identify the name input, for as fullname. But in doing so, nothing appears in my console.
Someone help me please.
$('form#form1').submit(function() {
var fname = $('input[name=fullname]').val()
var pho = $('input[name=phone]').val()
var mai = $('input[name=email]').val()
var amount = fname.split(' ').lenght
var splitStr = fname.split(' ')
if(amount >= 2) {
console.log('It worked!')
for(var i = 0; i < amount; i++ ) {
console.log(splitStr[1])
}
} else {
console.log("Wrong!")
return false;
}
return false;
}
It supposes to be fname.split(' ').length.
Writing fname.split(' ').lenght will result in amount == undefined and thus (undefined >= 2) will always be false.

I made a formula to extract some Wikipedia data in Google Seets which works fine. Here is the formula:
=regexreplace(join("",flatten(IMPORTXML(D2,".//p[preceding-sibling::h2[1][contains(., 'Geography')]]"))),"\[[^\]]+\]","")&char(10)&char(10)&iferror(regexreplace(join("",flatten(IMPORTXML(D2,".//p[preceding-sibling::h2[1][contains(., 'Education')]]"))),"\[[^\]]+\]",""))
Where D2 is a URL like https://en.wikipedia.org/wiki/Abbeville,_Alabama
This extracts some Geography and Education data from the Wikipedia page. Trouble is that importxml only runs a few times before it dies due to quota.
So I thought maybe better to use Apps Script where there are much higher limits on fetching and parsing. I could not see a good way however of using Xpath in Apps Script. Older posts on the web discuss using a deprecated service called Xml but it seems to no longer work. There is a Service called XmlService which looks like it may do the job but you can't just plug in an Xpath. It looks like a lot of sweating to get to the result. Any solutions out there where you can just plug in Xpath?
Here is an alternative solution I actually do in a case like this.
I have used XmlService but only for parsing the content, not for using Xpath. This makes use of the element tags and so far pretty consistent on my tests. Although, it might need tweaks when certain tags are in the result and you might have to include them into the exclusion condition.
Tested the code below in both links:
https://en.wikipedia.org/wiki/Abbeville,_Alabama#Geography
https://en.wikipedia.org/wiki/Montgomery,_Alabama#Education
My test shows that the formula above used did not return the proper output from the 2nd link while the code does. (Maybe because it was too long)
Code:
function getGeoAndEdu(path) {
var data = UrlFetchApp.fetch(path).getContentText();
// wikipedia is divided into sections, if output is cut, increase the number
var regex = /.{1,100000}/g;
var results = [];
// flag to determine if matches should be added
var foundFlag = false;
do {
m = regex.exec(data);
if (foundFlag) {
// if another header is found during generation of data, stop appending the matches
if (matchTag(m[0], "<h2>"))
foundFlag = false;
// exclude tables, sub-headers and divs containing image description
else if(matchTag(m[0], "<div") || matchTag(m[0], "<h3") ||
matchTag(m[0], "<td") || matchTag(m[0], "<th"))
continue;
else
results.push(m[0]);
}
// start capturing if either IDs are found
if (m != null && (matchTag(m[0], "id=\"Geography\"") ||
matchTag(m[0], "id=\"Education\""))) {
foundFlag = true;
}
} while (m);
var output = results.map(function (str) {
// clean tags for XmlService
str = str.replace(/<[^>]*>/g, '').trim();
decode = XmlService.parse('<d>' + str + '</d>')
// convert html entity codes (e.g. ) to text
return decode.getRootElement().getText();
// filter blank results due to cleaning and empty sections
// separate data and remove citations before returning output
}).filter(result => result.trim().length > 1).join("\n").replace(/\[\d+\]/g, '');
return output;
}
// check if tag is found in string
function matchTag(string, tag) {
var regex = RegExp(tag);
return string.match(regex) && string.match(regex)[0] == tag;
}
Output:
Difference:
Formula ending output
Script ending output
Education ending in wikipedia
Note:
You still have quota when using UrlFetchApp but should be better than IMPORTXML's limit depending on the type of your account.

Sorry I got very busy this week so I didn't reply. I took a look at your answer which seems to work fine, but it was quite code heavy. I wanted something I would understand so I coded my own solution. not that mine is any simpler. It's just my own code so it's easier for me to follow:
function getTextBetweenTags(html, paramatersInFirstTag, paramatersInLastTag) { //finds text values between 2 tags and removes internal tags to leave plain text.
//eg getTextBetweenTags(html,[['class="mw-headline"'],['id="Geography"']],[['class="wikitable mw-collapsible mw-made-collapsible"']])
// **Note: you may want to replace &#number; with ascII number
var openingTagPos = null;
var closingTagPos = null;
var previousChar = '';
var readingTag = false;
var newTag = '';
var tagEnd = false;
var regexFirstTagParams = [];
var regexLastTagParams = [];
//prepare regexes to test for parameters in opening and closing tags. put regexes in arrays so each condition can be tested separately
for (var i in paramatersInFirstTag) {
regexFirstTagParams.push(new RegExp(escapeRegex(paramatersInFirstTag[i][0])))
}
for (var i in paramatersInLastTag) {
regexLastTagParams.push(new RegExp(escapeRegex(paramatersInLastTag[i][0])))
}
var startTagIndex = null;
var endTagIndex = null;
var matches = 0;
for (var i = 0; i < html.length - 1; i++) {
var nextChar = html.substr(i, 1);
if (nextChar == '<' && previousChar != '\\') {
readingTag = true;
}
if (nextChar == '>' && previousChar != '\\') { //if end of tag found, check tag matches start or end tag
readingTag = false;
newTag += nextChar;
//test for firstTag
if (startTagIndex == null) {
var alltestsPass = true;
for (var j in regexFirstTagParams) {
if (!regexFirstTagParams[j].test(newTag)) alltestsPass = false;
}
if (alltestsPass) {
startTagIndex = i + 1;
//console.log('Start Tag',startTagIndex)
matches++;
}
}
//test for lastTag
else if (startTagIndex != null) {
var alltestsPass = true;
for (var j in regexLastTagParams) {
if (!regexLastTagParams[j].test(newTag)) alltestsPass = false;
}
if (alltestsPass) {
endTagIndex = i + 1;
matches++;
}
}
if(startTagIndex && endTagIndex) break;
newTag = '';
}
if (readingTag) newTag += nextChar;
previousChar = nextChar;
}
if (matches < 2) return 'No matches';
else return html.substring(startTagIndex, endTagIndex).replace(/<[^>]+>/g, '');
}
function escapeRegex(string) {
if (string == null) return string;
return string.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&');
}
My function requires an array of attributes for the start tag and an array of attributes for the end tag. It gets any text in between and removes any tags found inbetween. One issue I also noticed was there were often special characters (eg ) so they need to be replaced. I did that outside the scope of the function above.
The function could be easily improved to check the tag type (eg h2), but it wasn't necessary for the wikipedia case.
Here is a function where I called the above function. the html variable is just the result of UrlFetchApp.fetch('some wikipedia city url').getContextText();
function getWikiTexts(html) {
var geography = getTextBetweenTags(html, [['class="mw-headline"'], ['id="Geography']], [['class="mw-headline"']]);
var economy = getTextBetweenTags(html, 'span', [['class="mw-headline"'], ['id="Economy']], 'span', [['class="mw-headline"']])
var education = getTextBetweenTags(html, 'span', [['class="mw-headline"'], ['id="Education']], 'span', [['class="mw-headline"']])
var returnString = '';
if (geography != 'No matches' && !/Wikipedia/.test(geography)) returnString += geography + '\n';
if (economy != 'No matches' && !/Wikipedia/.test(economy)) returnString += economy + '\n';
if (education != 'No matches' && !/Wikipedia/.test(education)) returnString += education + '\n';
return returnString
}
Thanks for posting your answer.
EDIT: So the question is, why will my script not execute properly.
Edit 2: So this is the part that works as advertised and all items are predefined as number inputs prior too.
<script>
function Script5(){
var numeratorIn = document.getElementById("Numerator").value;
var denominatorIn = document.getElementById("Denominator").value;
var FACTOR = document.getElementById("FACTOR").value;
var Snum = document.getElementById("Snum").value;
var Sden = document.getElementById("Sden").value;
var x = document.getElementById("FinalAnswer");
x.style.display = 'none';
var x = document.getElementById("FinalDisplay");
x.style.display = 'block';
}
</script>
So I am working on a series of codes for a website I will be developing and this is a small subroutine for finding greatest common divisors. I am using Notepad++ for mobility purposes and trying to run my code in Google Chrome to start. I want to make a GCD function for variables (numeratorIn,denominatorIn). Again in HTML
This is the part I want to add into the same script
var a = Math.floor(Math.sqrt(numeratorIn));
var b = Math.floor(Math.sqrt(denominatorIn));
document.getElementById("midpage15").innerHTML = (+a);
var k = 1
if (a<b) {
while (k<a) {
if ((Snum/k == Math.floor(Snum/k)) && (Sden/k == Math.floor(Sden/k)); {
var h = k;
}
k = k++;
}
}
else if (a>b) {
while (k<b) {
if ((Snum/k == Math.floor(Snum/k)) && (Sden/k == Math.floor(Sden/k)) {
var h = k;
}
k = k++;
}
}
else (a == b) {
document.getElementById("midpage15").innerHTML = ("Final Answer 1");
}
But it breaks my button that I use to activate the script every time :(
I usually program in Python but I want to make this in HTML. So I spent about 5 hours working on it and it is just driving me nuts. I am 100% confident it has something to do with the Ifs and the while statements at the bottom.
Here Snum and Sden are string.So you need to convert it into integer first.For that you can use parseInt() function.
I'm trying to make a script for google sheet, who can count a letter in a text. But it seems that .length doesn't work. Anyone who can give directions on where to find the the solution.
function Tjekkode(tekst , bogstav){
var test = "";
// find the length of laengdeTekst
var laengdeTekst = tekst.length;
var t = 0;
// through the text character by character
for ( var i = 1; i<laengdeTekst ; i++) {
var test = tekst.substr(i,1);
if (test == bogstav) {
// if the letter is found, it is counted up
// REMEMBER == means compare
var t = t + 1;
}
}
// returns percent appearance of the letter
Return = t / længdeTekst * 100
}
Thanks in advance
length is ok in your code. To test it, run this script:
function test( ) {
var test = "123456";
// finder længden på teksten
var laengdeTekst = test.length;
Logger.log(laengdeTekst);
}
After you run it, check Log, press [Ctrl + Enter]
The correct code in your case:
function Tjekkode(tekst, bogstav) {
var test = "";
var laengdeTekst = tekst.length;
var t = 0;
// start looping from zero!
for ( var i = 0; i<laengdeTekst; i++) {
var test = tekst.substr(i,1);
if (test == bogstav) {
var t = t + 1;
}
}
// JavaScript is case sensitive: 'return != Return'
return t / laengdeTekst * 100;
}
Please, look at this tutorial for more info
thanks
I'll guess that I might get the one with the R instead of r at the end, but the script didn't run that line, because it kinda stopped at the .length line :/
the comments in danish is for my pupils (I'm a teacher in elementary school)
I'll see if google wants to cooperate today :|
This is the google script that worked for me. Note the 24 - that's the length of an empty message that has markup like <div>...</div>
function TrashEmptyDrafts() {
var thread = GmailApp.getDraftMessages();
for (var i = 0; i < thread.length; i++) {
b=thread[i].getBody();
if (b.length <= 24.0){
thread[i].moveToTrash();
}
}}
I have twenty eight instances of a two-frame MovieClip (frame1 = off - frame 2 = on) to select PDFs to send. The following code works fine, but I am looking to tighten it up and make it less verbose and easier to read. I include only one reference to an instance for space and sanity sake.
function PDFClick(e:MouseEvent):void {
targetPDF = e.target.ID;
trace("targetPDF " +targetPDF);
if (targetPDF == "PDF1")
if (pdf.pcconnectionPDF1.currentFrame == 1)
{
pdf.pcconnectionPDF1.gotoAndPlay(2);
PDF1 = 1;
trace("PDF1 is "+PDF1);
}else{
pdf.pcconnectionPDF1.gotoAndPlay(1);
PDF1 = 0;
trace("PDF1 is "+PDF1);
}
Thanks! trying to learn
You'll want to generalize your calls to your ID, that way you don't need special code for each condition.
function PDFClick(e:MouseEvent):void {
var ID:String = e.target.ID;
var mc = pdf["pcconnection" + ID];
if (mc.currentframe == 1) {
mc.gotoAndPlay(2);
this[ID] = 1;
} else {
mc.gotoAndPlay(1);
this[ID] = 0;
}
}
How about this:
function PDFClick(e:MouseEvent):void {
targetPDF = e.target.ID;
trace("targetPDF " +targetPDF);
if (targetPDF == "PDF1") {
var frame:int = pdf.pconnectionPDF1.currentFrame;
pdf.pconnectionPDF1.gotoAndPlay( frame == 1 ? (PDF1 = 1)+1 : (PDF1 = 0)+1 );
}
}
I think that's about what you are looking for.
So basically I would like to create a function that when alerted, returns the URL from an array (in this case the array is declared as 'websites'). The function has two parameters 'websites' and 'searchTerm'.
I'm struggling to make the function behave, so that when i type yahoo or google or bing in the searchTerm parameter for the function; I want it to return the corresponding URL.
Any help or support would be greatly appreciated.
Sorry if I have not made myself clear in my explanation, if this is the case, let me know and I will try and be clearer in my explanation.
Thanks in advance!
Try something more like:
var websites = {google: 'www.google.com', yahoo: 'www.yahoo.com'};
function filterURL(websites,searchTerm)
{
return websites[searchTerm] || 'www.defaultsearchwebstirehere.com';
}
** Update following comment **
Build up your websites object like so (where input is your array of key values seperated by pipe characters):
var websites = {};
for (var i = 0; i < input.length; i++) {
var siteToSearchTerm = input[i].split('|');
websites[siteToSearchTerm[1]] = siteToSearchTerm[0];
}
Here is how:
var websites = ["www.google.com|Google" , "www.yahoo.com|Yahoo" , "www.bing.com|Bing"];
function filterURL(websites,searchTerm)
{
for (var i = 0; i < websites.length; i++) {
if (websites[i].split('|')[1] === searchTerm) {
return websites[i].split('|')[0];
}
}
}
Working Example
You can also validate and improve function:
function filterURL(websites,searchTerm)
{
if (typeof websites != 'Array' || ! searchTerm) return false;
for (var i = 0; i < websites.length; i++) {
if (websites[i].split('|')[1] === searchTerm) {
return websites[i].split('|')[0];
}
}
return false;
}
Why not just use an object?
var websites = {
Google: 'www.google.com',
Yahoo: 'www.yahoo.com'
};
function filterURL(sites, searchTerm) {
if (sites[searchTerm]) {
return sites[searchTerm];
} else {
// What do you want to do when it can't be found?
}
}
alert(filterURL(websites, 'Google')); // alerts 'www.google.com'
You should really be using a hash-table like structure so that you don't have to search through the whole array every time. Something like this:
var websites = {
"Google": "www.google.com",
"Yahoo": "www.yahoo.com",
"Bing": "www.bing.com"
};
function filterURL(websites, searchTerm) {
if (websites[searchTerm] !== undefined)
return websites[searchTerm];
else
return null;
}
I'm not sure why you want to use an array for this, as what you're really doing fits a key-value pair better; however, here's how I'd do it:
function filterURL(websites, searchTerm) {
var i = 0,
parts;
for (i = 0; i < websites.length; i++) {
parts = websites[i].split("|");
if (parts[1].toLowerCase() === searchTerm) {
return parts[0];
}
}
}
But consider if you used a proper JavaScript Object instead:
var websites = {
Google: "www.google.com",
Yahoo: "www.yahoo.com",
Bing: "www.bing.com"
}
// Now it's much simpler:
function filterURL(websites, searchTerm) {
// key has first letter capitalized…
return websites[searchTerm.charAt(0).toUpperCase() + searchTerm.slice(1).toLowerCase()];
}
