My drop down menu has genres that it displays, but numbers as the values, eg
<option value=240>Alternative Rock</option>
My POST data deals with just the value - that's all I need for my database, and it works fine.
However, I'd like to display the selected option after submission, which I would normally do like this if the option and value are the same...
if ( isset($_POST['genre']) && $_POST['genre'] != "" && $_POST['genre'] != "undefined" ) echo stripslashes(htmlentities($_POST['genre'])); else echo 'All';
But since they are not the same, after submission the above example now displays "240" as it's selection, not "Alternative Rock".
How do I get it to remember the display option, not just the value, while still getting the numerical value that my database queries need?
Thanks for taking a look.
The POST is not going to include the disable value by default. There are a couple options... You can store all the options on the server side while the original page is being created (for example, in a session variable), and then look up the display value when the POST comes in. Or you can use JavaScript to set a hidden form element with the display value, when the user submits the form.

I am trying to organize a drop down list that will display a single value to the user but will also pass back an array object upon changing the selection.
Currently I have an array called classificationresult that has 3 elements CLASSIFICATION_NAME, GROUP_ID, GROUP_NAME.
When a user selects a particular CLASSIFICATION_NAME I want to pass back the entire array result containing all 3 elements listed above.
Currently the code below works for everything EXCEPT showing the CLASSIFICATION_NAME in the drop-down box upon loading. It shows the list once you click, but it starts with a blank until it is clicked. Any way to fix this? I believe the display element is tied to [ngValue] but that is also what I am using to pass back the entire array versus just the one.
Any help would be greatly appreciated.
<p>Select Classification*</p>
<select [(ngModel)]="selectedClassification (ngModelChange)="changedClassification($event)">
<option *ngFor="let classificationresult of classificationresults" [ngValue]="classificationresult" >{{ classificationresult.CLASSIFICATION_NAME }}</option>
</select>
Summary -- I want my drop down list to always have a value shown to the user (value being the Classification Name) but when one is selected I want the entire array to pass to the changedClassification function. Also sometimes after a user selects from other drops down on this page they will also go blank, but if they are selected a second time they will populate.
If everything is working as you are expecting except the initial value being displayed, I wonder if you need a [compareWith] function. I don't know what your classificationresult model looks like, but if I had to take a guess, putting a [compareWith] function on your <select> element would fix the issue.
Here is an article explaining it a little more.
I made this Stackblitz as an example with using the [compareWith] function. In my demo I am using ReactiveForms, but the compareWith should still be the same.
For your code, it may look something like:
<p>Select Classification*</p>
<!-- add this [compareWith] -->
<select [compareWith]="myCompareFunc" [(ngModel)]="selectedClassification" (ngModelChange)="changedClassification($event)">
<option *ngFor="let classificationresult of classificationresults" [ngValue]="classificationresult" >{{ classificationresult.CLASSIFICATION_NAME }}</option>
</select>
In your .ts file:
export class YourComponent {
// all your component code..
/* compare function, change the logic to fit your needs */
myCompareFunc (classificationRes1: any, classificationRes2: any): boolean {
return classificationRes1 && classificationRes2
? classificationRes1.CLASSIFICATION_NAME === classificationRes2.CLASSIFICATION_NAME
: classificationRes1 === classificationRes2
}
}
If that doesn't fix your issue, you may need to post more of your .ts code and data models.
I'm quite new to VBA and I've been looking around but cannot seem to find a solution to my problem.
I have made a navigation form (frmNavigation) with 3 buttons, each referring to a different form, let's call them frm1, frm2 and frm3. In the navigationform the control buttons to switch between tabs are all named differently (btn1, btn2, btn3), but the subform that shows either frm1, frm2, or frm3 has the same name: “NavigationSubform” (this shows a different form depending on which tab is clicked on, based on the 'navagation target name' referring to frm1, frm2 and frm3).
When I want to refer to a textbox (txtBox1) on form 1 (first tab) and insert a value i can do this by:
Forms!frmNavigation!NavigationSubform.Form!txtBox1.Value = "insert awesome text"
But how would I refer to txtbox10 on the second tab (frm2)? Just using the following does not work:
Forms!frmNavigation!NavigationSubform.Form!txtBox10.Value
You then get the error 2465 (can't find the field).
I’ve been trying many different things, but can’t seem to get it right. So how do I refer to a textbox on a different tab than the first one?
Help us much appreciated!
Only one subform can be loaded at once. So you've just got to break this process into two steps.
Store the value from txtBox1 somewhere outside of the NavigationSubforms (a textbox on the parent form with visible = no, a global variable or a table works).
In frm2's On Load event, set txtbox10 to be the value you stored.
Just note, that you will need to add conditions in the On Load event if you want to avoid that textbox being set to an empty string or a wrong value if you have a setup where your filter is changing.
I am using the djFilteringSelect control to show values in a dropdown as user type a value.
The lookup and typehead is working fine. The user type a letter and the dropdown allow the user to select a value which is then displayed in the dropdown field.
If the user now decide to remove the value first selected so that the combobox is empty and leave the field, then the first value in the list is now automatically filled in.
The consequence of this is that if the user have added a value there is no way to remove the value and leave the box emtpy.
I am using required=false for both the control and the dojo attribute but it does not seem to help. There are also a few other djFilteringSelect attributes I have tried like "Autocomplete" and "trim" but it does not work
Here is the code
<xe:djFilteringSelect id="test" type="select" store="jsondata" searchAttr="data" required="false" labelType="html" invalidMessage="Not valid">
<xe:this.dojoAttributes>
<xp:dojoAttribute name="required" value="false"></xp:dojoAttribute>
</xe:this.dojoAttributes>
</xe:djFilteringSelect>
Initally the field is not required, but if the user have entered a value it is required.
My question is if there a way to prevent the djFilteringSelect control to always populate the field if I have previously added a value
I found someone who solved this in another stack overflow topic, by creating an empty entry in my data store. but I could not get this to work
Dojo: Select of empty value for FilteringSelect while required=false
I do this quite a lot. Right now I don't have a working sample to show you (since I moved to bootstrap - and have to code the selects by manually adding select2 controls) but something like this should do it...
I add an "empty" value at the top of my select - and that seems to work no matter whether I am using a combobox, djCombobox or combobox with select2 from bootstrap. My markup typically looks like:
<xp:comboBox id="inputLocationSelector" value="#{User.catchListType}" disableClientSideValidation="true">
<xp:selectItem itemLabel="(none)" itemValue=""></xp:selectItem>
<xp:selectItems>
<xp:this.value><![CDATA[${Configuration.meta.listLocationTypeOptions}]]></xp:this.value>
</xp:selectItems>
</xp:comboBox>
Then you could specify "(none)", "All" or " " for the "not-selected" value depending on your needs.
Validation is a different thing so just specifying "required=false" does not give you the "empty" value.

I have a simple HTML page with an Unordered list. Is it possible to have an input field where you could add more to the list and it would be saved after you submitted it. What I would like to add would be the content inside of an <li> tag as well as the <li> tags themselves.
Thanks,
Here is a jsfiddle with a demo of what I think you want to achieve: http://jsfiddle.net/mvJNq/25/
Note that I can not answer as to how you should do this on the server, as that depends on how your serverside code, database etc is set up. However, if all you want is to display it as HTML and not have it saved as the user navigates away, you won't need the Submit button at all - then you just need the "Add" functionality.
Yes, it is possible - no, it will not be pretty. Here is what you would do:
create your base form with any default list items/inputs
use jQuery/JavaScript to bind an event handler to a button that you click when you want to add another item (alternatively, you could skip this step and just have another item appear by default)
on your event (be it checking that all input boxes have user-entered text, or the click event in step two) add another list item using jQuery.append(...)
ensure that you have a hidden input field to be used as a "counter" to keep track of the total number of list items and increment the value of this counter each time you add a new list item (note: you may need to use the ParseInt() method, depending on how you design the code for this field)
the page that is receiving the form's inputs should first read the hidden field so that it knows how many items to add, and then you should loop through the items (for or while loop) to add them correctly
Note: I don't know what Server-Side language you are using to handle receiving the form so step 5 is a fairly generic and universally viable option
Sure, it's possible.
The complexity of this comes in when you want to "save" the items. If the user leaves the page and comes back later will that data be available? If so, you will need a database like mySQL or similar. The li tags can be stored as well, but why?
If you just need that information available in that session you can store in a JavaScript variable and have it loop through the variable and spit them out as <li>'s
If you did want to use an add button instead of submit:
$('#addButton').click(function(){
var savedContent = $('#input').val();
}
To create + insert the <li>you can use javascript to create the element and append it to the ul. If you have more than one ul change the index:
var content = document.createElement('li');
content.innerText = savedContent;
document.getElementsByTagName('ul')[0].appendChild(content);
Am trying to make a game using Html5. my need is i have menu html page with 3 buttons one,two,three. when am clicking on that button am storing that value like one or two or three storing in a variable and it'll go to next page game.html. and i can retrieve it too.
localStorage.setItem("value",$(this).val()); //storing 1,2 or 3 in value
var value_menu = localStorage.getItem("value"); //getting value in value_menu
here i have a back button in game.html page, if i click on that it'll go to menu page and am removing the key values from localstorage.
localStorage.removeItem("value"); (or) localStorage.clear();
if am again click on the buttons in menu page, the value showing as null. why its showing as null ? because if i click on button the localstorage have to store value again. isn't it?
otherwise am making any mistakes? need some explanations.
thank u in advance.
Because null is the default value when something does not exist and you delete the value when yo go back so it is "logic" .... the value is null because it does not exist because you remove it.
Okay? ;-)
You can interpret null as 'not selected' (in your case it IS not selected and that's true because you have deleted it when the user go back). The next thing you have to do is to check if the value is null (value === null) and to do nothing when it is null (not showing it). Or much better: if( typeof value == "number" && value > 0 ) etc.
It think it is better to not remove the choice of the user until the user left the first/entry page.
Pure interest: What kind of game do you want to create?
