hi i need to hide empty UITableViewcell label in custom TableView.i am trying to display JSON webservice values in custom tableviewcell.
my json vales are looks like ...
(
{
post = {
"CLASS_LEVEL" = "Intro/General";
"CLASS_TYPE" = "Muay Thai";
"DAY_OF_WEEK" = "";
ID = 19;
"ORDER_BY" = 5;
TIME = "1:00pm - 2:30pm";
};
}
{
post = {
"CLASS_LEVEL" = "General/Intermediate/Advanced";
"CLASS_TYPE" = "Muay Thai Spar - Competitive";
"DAY_OF_WEEK" = "";
ID = "";
"ORDER_BY" = 5;
TIME = "6:00pm - 9:00pm";
};
},
{
post = {
"CLASS_LEVEL" = "Fighters/Advanced/Intermediate";
"CLASS_TYPE" = "Fighters Training";
"DAY_OF_WEEK" = Monday;
ID = 1;
"ORDER_BY" = 1;
TIME = "";
};
},
i need to auto size my table cell dynamically .
here some of values are empty that values assigned label in tableviewcell want to be hidden.
is it possible? help me .Thanks in advance
To hide the UILabel you can just do cell.label.hidden = YES;
You can try this
NSString *dayOfWeek = ... ;
if(dayOfWeek == (id) [NSNull null] || [dayOfWeek length] == 0 || [dayOfWeek isEqualToString:#""])
{
cell.label.hidden = YES;
}
else
{
cell.label.hidden = NO;
}

I am using amcharts4 plugin to plot a multi-lineseries graph.
But the plotted points do not locate at the right position (Blue dot at the edge of y-axe)
Here is the output chart that I get. (pls see the attached above)
Not sure what had done wrong with the following codes. Hope someone can help me out.
Thanks in advance!
var chart = am4core.create("chartdiv", am4charts.XYChart);
//Create axes
var categoryAxis = chart.xAxes.push(new
am4charts.CategoryAxis()); categoryAxis.dataFields.category = "date";
categoryAxis.title.text = "Month-Year";
categoryAxis.title.fontWeight = "bold";
/* Create value axis */
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
valueAxis.title.text = "Total Sales ($)";
valueAxis.title.fontWeight = "bold";
/* Add data */
var ds = new am4core.DataSource();
ds.url = window.location.origin+"/home/salesVolumnVersusPeriod"; //Sample of external JSON DATA = [{"date":"02-2020","FS":6288, 'IO':2342}]
ds.events.on("done", function(ev) {
chart.config = ev.data;
var u = ev.data; var data =
ev.target.data[0]; var datakey = Object.keys(data);
var text = '';
for (var i = 1; i < datakey.length; i++) {
addSeries(datakey[i], u);
text += datakey[i]+' : {'+datakey[i]+'}'+"\n";
}
$('#chartdiv').append('<div id="test">'+text+'</div>');
});
ds.load();
/* Create series */
function addSeries(b, data) {
// Create series
var series = new am4charts.LineSeries();
series.data = data;
series.dataFields.valueY = b;
series.dataFields.categoryX = "date";
series.name = b;
series.strokeWidth = 3;
series.tensionX = 0.7;
series.bullets.push(new am4charts.CircleBullet());
series = chart.series.push(series);
series.events.on("hidden", updateTooltipText);
series.events.on("shown", updateTooltipText);
}
function getToolstipItemValue(text) {
return `[bold]Date {categoryX}[/]
---- `+text;
}
/* Set up tooltip attachment to other series whenever series is hidden */
function updateTooltipText() {
var added = false;
tooltipText = $('#test').text();
chart.series.each(function(series)
{
if (series.visible && !added) {
series.tooltipText = getToolstipItemValue(tooltipText);
added = true;
}
else {
series.tooltipText = "";
}
});
}
/* Add legend */
chart.legend = new am4charts.Legend();
/* Create a cursor */
chart.cursor = new am4charts.XYCursor();
Finally knew what is wrong. It should use chart.data instead of chart.config.
Now the graph works. Hope this could help you too. Cheers!
chart.config = ev.data;
I want to convert a formatted text in a cell to html but I don't know how to read the format of the text.
Let's say that I have the following text in a cell:
A text with a bold word.
And I would like to convert it in an other cell to:
A text with a <b>bold</b> word.
How can I do that?
I didn't find anything useful in the Spreadsheet API to read format info...Does anyone have any tips?
Thanks.
EDIT: I've created a feature request. Please vote to have the feature.
My Google Script
/**
* Rich Text to HTML.
* #param {string} qRange Input text.
* #returns {string} Text as HTML.
* #customfunction
*/
function RICHTEXT_TO_HTML(qRange) {
var indexBool = false;
var indexItalic = false;
var indexUnderline = false;
var indexStrikethrough = false;
var sheet = SpreadsheetApp.getActiveSpreadsheet();
var range = sheet.getRange(qRange);
var cell = range;
var cellValue = cell.getRichTextValue();
var txt = String(cell.getDisplayValue());
var styles = cell.getTextStyles();
var result = '';
for (var i = 0; i < txt.length; i++) {
var style = cellValue.getTextStyle(i, i + 1);
if (!indexStrikethrough && style.isStrikethrough()) {
indexStrikethrough = true;
result += '<strike>';
} else if (indexStrikethrough && !style.isStrikethrough()) {

}
Usage
A1 = "My formatted example!!!"
A2 = =RICHTEXT_TO_HTML("A1")
A2 Result = My <i>formatted</i> <b>example</b>!!!

I went ahead and updated this idea to better reflect how we do this is 2021.
/**
* #Author: Emma Sargent

*/
function richTextToHtml(range) {
const runs = range.getRichTextValue().getRuns();
const formattedRuns = runs.map((run) => {
const attr = {
style: '',
};
const text = run.getText();
const link = run.getLinkUrl();
let parentTag = 'span';
if (link) {
parentTag = 'a';
attr.href = link;
}
const style = run.getTextStyle();
const styles = {
'font-family': `'${style.getFontFamily()}'`,
'font-size': `${style.getFontSize()}px`,

};
attr.style = Object.entries(styles)
.map(([key, val]) => `${key}: ${val}`)
.join('; ');
let tags = [];
if (style.isBold()) {
tags.push('b');
}
if (style.isItalic()) {
tags.push('i');

}
const headTags = tags.length ? `<${tags.join('><')}>` : '';
const closeTags = tags.length ? `</${tags.join('></')}>` : '';
const attrStr = Object.entries(attr)
.map(([key, val]) => `${key}="${val}"`)
.join(' ');
const mainTag = `<${parentTag} ${attrStr}>${headTags}${text}${closeTags}</${parentTag}>`;
const lineBreakFormattedStr = mainTag.replace(/[\r\n]/g, '<br>');
return lineBreakFormattedStr;
});
return formattedRuns.join('');
}
And because someone emailed me and asked, here's a version that can be run as a custom function from the formula bar.
Spreadsheet formula: =richTextToHtml("YourSheetName!A1NotationRange")
function richTextToHtml(rangeStr) {
let [sheetName, rangeName] = rangeStr.split("!");
sheetName = sheetName.replaceAll("'",'');

const runs = range.getRichTextValue().getRuns();
const formattedRuns = runs.map((run) => {
const attr = {
style: '',

const text = run.getText();
const link = run.getLinkUrl();
let parentTag = 'span';

Here's a version that creates more compact HTML (avoiding lots of spans setting styles):
function richTextToHtml(range) {
let lastFont = null, lastSize = null, lastColor = null, lastLink = null;
let parentClose = '';
return range.getRichTextValue()
.getRuns()
.map(run => {
const text = run.getText().replace(/[\r\n]/g, '<br>');
const style = run.getTextStyle();
const font = style.getFontFamily();
const size = style.getFontSize();
const color = style.getForegroundColor();
const link = run.getLinkUrl();
let mainTag = '';
if (font !== lastFont || size !== lastSize || color !== lastColor || link !== lastLink) {
mainTag += parentClose;
mainTag += link ? `<a href="${link}"` : '<span';
mainTag +=
` style="font-family:'${font}';font-size:${size}px;color:${color}">`;
parentClose = link ? '</a>' : '</span>';
lastFont = font;
lastSize = size;
lastColor = color;
lastLink = link;
}
let closeTags = '';
Object.entries({isBold: 'b', isItalic: 'i', isUnderline: 'u', isStrikethrough: 'strike'})
.filter(([getter, tag]) => style[getter]())
.forEach(([getter, tag]) => {
mainTag += `<${tag}>`;
closeTags = `</${tag}>${closeTags}`;
});
return `${mainTag}${text}${closeTags}`;
})
.join('') + parentClose;
}
You need to use getFontWeight properties of the Range to read these formating values. Example given here: GAS-check-cell-format

i'm trying to sort an arraycollection that uses letters and numbers
Currently I'm getting "b12,c1,b1,b3,b4,b5,b6,b7,b8,b9,b10,b11,b0,b13,b14,b15" but want "b0,b1,b2,b3,b4,b5,b6,b7,b8,b9,b10,b11,b12,b13,b14,b15,c1"
Please can anyone suggest when're I have gone wrong?
var dataSortField:SortField = new SortField();
dataSortField.name = "order";
dataSortField.numeric = false;
dataSortField.compareFunction = sortAlphaNumeric;
var numericDataSort:Sort = new Sort();
numericDataSort.fields = [dataSortField];
pageArrCol.sort = numericDataSort;
private function sortAlphaNumeric(a:String, b:String):int {
var reA:RegExp = /[^a-zA-Z]/g;
var reN:RegExp = /[^0-9]/g;
var aA:String = a.replace(reA,"");
var bA:String = b.replace(reA,"");
if (aA === bA) {
var aN:int = parseInt(a.replace(reN,""),10);
var bN:int = parseInt(b.replace(reN,""),10);
return aN === bN ? 0 : aN > bN ? 1 : -1;
} else {
return aA > bA ? 1 : -1;
}
}
myArrayCollectionToSort.source.sortOn("order", sortAlphaNumeric);
private function sortAlphaNumeric(a:String, b:String):int {
var reA:RegExp = /[^a-zA-Z]+/g;
var reN:RegExp = /[^0-9]+/g;
var aA:String = a.match(reA)[0];
var bA:String = b.match(reA)[0];
if (aA == bA) {
var aN:int = parseInt(a.match(reN)[0],10);
var bN:int = parseInt(b.match(reN)[0],10);
return aN == bN ? 0 : aN > bN ? 1 : -1;
}
return aA > bA ? 1 : -1;
}
I don't test it but it should works, and array is way faster than an ArrayCollection. (arraycollection.source is an array). If the sorted ArrayCollection is binded you need to dispatch a refresh event if you want the bind to works:
myArrayCollectionToSort.dispatchEvent(new CollectionEvent(CollectionEvent.COLLECTION_CHANGE, false, false, CollectionEventKind.REFRESH));
or
myArrayCollectionToSort.refresh();
Assuming that b12,c1,b1 is your input format
You may have meant, a.match(regex)[0]
var reA:RegExp = /[a-zA-Z]+/g;
var reN:RegExp = /[0-9]+/g;
var aA:String = a.match(reA)[0];
var bA:String = b.match(reA)[0];
if (aA === bA) {
var aN:int = parseInt(a.match(reN)[0],10);
var bN:int = parseInt(b.match(reN)[0],10);
return aN === bN ? 0 : aN > bN ? 1 : -1;
}else {
return aA > bA ? 1 : -1;
}
I have not tested this, but you should not be using replace, use match instead. Also, the regular expression is wrong. You have to revisit the regular expression.
I make service from json but i have problem to show url in json, this url http://git.drieanto.net/LagiDimanaAPI/index.php/user/get_following/1 i try to show url from database but in json show "avatar":"http:\/\/git.drieanto.net\/LagiDimanaAPI\/assets\/image\/avatar\/edwin.png".
how to make to show normal url like this http://git.drieanto.net/LagiDimanaAPI/assets/image/avatar/edwin.png
i used codeigniter this the code
function get_following($id_follower) {
if ($this->muser->cek_following($id_follower) == TRUE) {
$query = $this->muser->get_list_id($id_follower);
$feedback["following"] = array();
foreach ($query->result() as $row) {
$query_list_user = $this->muser->get_all_name_user_from_id($row->id_user);
if ($query_list_user->num_rows() > 0) {
$row_ = $query_list_user->row();
$query_status = $this->muser->get_status($row_->id_user);
$query_status->num_rows();
$row2 = $query_status->row();
$response['status'] = $row2->status;
$response['regid'] = $row_->regid;
$response['id_user'] = $row_->id_user;
$response['email'] = $row_->email;
$response['nama'] = $row_->nama;
$response['jenis_kelamin'] = $row_->jenis_kelamin;
$response['tanggal_lahir'] = $row_->tanggal_lahir;
$response['instansi'] = $row_->instansi;
$response['jabatan'] = $row_->jabatan;
$response['avatar'] = $row_->avatar;
$feedback['success'] = 1;
} else {
$feedback['success'] = 0;
}
array_push($feedback["following"], $response);
}
$feedback['success'] = 1;
echo json_encode($feedback);
} else {
$feedback['success'] = 0;
echo json_encode($feedback);
}
}
thanks
It's just escaping the forwardslashes. You can use str_replace($search_char, $replace_char, $string_to_search), to remove them.
$stuff = json_decode($response);
$url = str_replace("\\", "", $stuff['url']);
It does sound like you're not decoding the JSON because I do believe PHP will unescape all of that stuff for you automatically.
In EXTJS i will use a model and store for my grid. Now is the problem that sometimes the json will not match the model. There will be less information then in my model. When this happens EXTJS will not show any data in the grid. So i looked for a fix and found this:
Ext.define('App.Reader', {
extend: 'Ext.data.reader.Json',
extractData: function(root) {
var me = this,
values = [],
records = [],
Model = me.model,
i = 0,
length = root.length,
idProp = me.getIdProperty(),
node, id, record;
if (!root.length && Ext.isObject(root)) {
root = [root];
length = 1;
}
for (; i < length; i++) {
node = root[i];
values = me.extractValues(node);
id = me.getId(node);
record = new Model(values, id, node);
records.push(record);
if (me.implicitIncludes) {
me.readAssociated(record, node);
}
}
return records;
},
extractValues: function(data) {
var fields = this.getFields(),
i = 0,
length = fields.length,
output = {},
field, value;
for (; i < length; i++) {
field = fields[i];
value = this.extractorFunctions[i](data);
if(value === undefined)
{
Ext.iterate(fields, function(key, val) {
if (data[key] === undefined & i==val) {
console.log( "Model field <" + key.name + "> does not exist in data/node.");
value = "INVALID OR MISSING FIELD NAME";
var p = 0;
for(var prop in data) {
if(p==i){
if(data.hasOwnProperty(prop))console.log("Instead of <" + key.name + "> we have <" + prop + "> with value <" + data[prop]+ ">");
}
p++;
}
}
}, this);
}
output[field.name] = value;
}
return output;
}
});
var myReader = new App.Reader({
type:'json'
});
i found this online. But when i use this with EXTJS 4.1.1 there is an error in ext-all: TypeError: j is undefined.
Where should i look for the fix for this?
There's no need to do something complicated to solve this trivial problem. Read up on Ext.data.Model and Ext.data.Field, configure your Model properly and you're all set.
