JQuery :: Dynamically Created Select Option Not Working?
Jun 24, 2011
I am creating a dynamo form but <select and <option does not show.
How do I make sure that they are created on the fly?
jQuery("#dump_data_box").append('<select id="thisid" name="value_name[]">');
and later
jQuery("#dump_data_box").append('<option');
///
if (v==k2) jQuery("#dump_data_box").append(' selected ');
//
jQuery("#dump_data_box").append(' value="'+k2+'">'+k2+'</option>');
In IE the selection box is created, and there is a drop-down box if I click on the down arrow, but I can't see the OPTION text for each option. The options are invisible, yet the box seems fully functional. I went into the debugger and sure enough the selection box has "OPTION" child nodes with the correct "value" and "text" attributes.
According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.
Trying different options I came out with this approach that seems to do the job so far:
function setSelect(pID,pSelectedValue) { $('#'+pID + ' option:selected').removeAttr('selected');
i have several programmatically generated DIVSectionsin my WebApplication. And i have for each of these DIVSectiona RadioButton Group. When the user now checks the RadioButton of the associated DIV-Section theSectionshould be Shown. And when he checks the other RadioButton the DIVSectionshould be hidden.How could a jQuery Function and a call look like, which does the above action?Here my sample:
I'm creating some rows and cells in a table with javascript. I'm then trying to select these cells individually by id, but jquery can't seem to find them. It always returns length 0. The jquery code is, I believe, executing after the cell creation, so I would expect them to be in the DOM already. I can bind the click event to each cell by selecting the cell's class. Why can I select the class, but not the id? It would be nice to be able to do this rather than iterate through each cell in the class.
I'm currently working with a bit of javascript to dynamically add <option>s into a select box. My code currently works fine in Internet Explorer, however in Firefox the dropdown only displays the first option in the list, and when clicked the other values aren't displayed.
Here is the code;
//ar_options is an array with the option to be displayed in.
for (count=0; count<number_of_options+1; count++) { document.forms['enquiry'].enquirytype.options[count] = new Option(ar_options[count],ar_options[count]); };
As I said - fine in Internet Explorer, but not in Firefox. I did discover some discussions about this, which were talking about an issue and workarounds but I couldn't get any of them to work. I have also tried simply using the document.write() function to output the HTML in the correct place. However this is just hte same, works in IE but not Firefox.
I've got a snippet of code I'm trying to write and I have worked out how to extract from an option the value and its id but can't seem to see how to match it to its select.
HTML Code:
var table = document.getElementById("x"); var option = table.getElementsByTagName("option"); for (var i = 0; i < option.length; i++) {
I'm building a t-shirt shop whose interface includes a gallery of designs in an IFrame. When the user clicks on a design, a dedicated page is loaded into the IFrame which shows all the available products associated with the design the user clicked.
I've put each design's image and associated page as the first and second elements of a nested array, and am using a for loop to then load all the images into the page that's shown in the IFrame when the web-site loads. It's looking beautiful, but here's the rub I've been stuck on for two days now with no solution in sight...
The array, "designImages", has 37 elements (ie. designImages[0]... designImages[36]). When I click on a design image on the page, any design image, the browser (all browsers, so I can't blame Microsoft for this one :rolleyes: ), loads the page for design #36. I've tried all sorts of things, but still cannot tell if the issue is because the dynamically generated divs are being reassigned the value [36] after the for loop's executed, or if the div id's are okay but somehow the code is rooting for [36], the last element of the array anyway.
I'm using the following code to remove an option from a select control based on a selection in a different select control and the option text in the select option that is being removed. The code works as I want it to, but I would prefer to use the option value for identifying the option to remove instead of using the option text. I've tried several different ways to do this, but can not find the proper syntax.
I dynamically create a textbox as follows, but I cannot retrieve the value entered by the user:
bp_boards = ' <tr id="hwNumberBoards"> <td>No. of modules:</td>[code]....
The dynamically created textbox shows up on the page but after the user enters a value, I cannot retrieve it from jquery(alert ($("#hwNumberBoards").val()) is "undefined")
I am creating Textboxes at Runtime with something like this code...
and what this function does it count the number of Characters that have been typed in a Textbox. so i am displaying the remaining characters. So that is working fine on my example because the Element is known at Early Binding. Now my question is what if the textbox is created dynamically ?
contentbox
this is the name of the Textbox in my example.
how do we use a J Query in Dynamically created Textbox.
How to add an ID to dynamically created input field. Type of serial Input field its possible to add, but If I insert any input field in the middle is the problem for me.
Add/Delete of the input field is happening like this [URL]... How to add the ID for the input field
I'm using some javascript to generate multiple input text fields with the same name of additionalDate[] but cant seem to get datepicker to work on it.Here is the datepicker code:
I have recently started exploring the world of jQuery and it looks incredibley rich and powerful! I am stuck on something, though. When I dynamically create a div
var divTag = document.createElement("div"); //Set the parameters divTag.id = "divMaster"; //Create it and immediately hide it!
[Code].....
This is probably really obvious, but I cannot figure out why? Perhaps jQuery is looking for elements already in the original HTML, and my div tag was added to the DOM after loading the original elements?
The code below creates images based on a json feed, no problem. All images are created and the click function works perfectly, but... I can't access any of the images by their id's so I can't make thefunctionbehave as I wan't.
I first thought jQuery appended my image object as html and didn't insert it as a valid object in the dom, but as the click function is working that can't be it?
I found some other people had the same problem but they were using vanilla js, their solution was using .appendChild() but thatdoesn'twork in jQuery.
I can see the raw HTML in firebug etc, but the dynamic elements (the ones created by jquery for example), obviously don't appear there. I struggle referencing some of them - Ideally I'd like to be able to trigger a display showing what handle to use for any given element - for example by clicking on them.
i created image links by reading an xmland creating the img and a tags in jquery. how do i put a function init? i tried the function below but it doesnt seem to work. These imagelinks are stored in the div: "thumbs"Below is the code:
After loading a HTML fragment using AJAX, I can not select the newly embedded elements using the $("#id") notation. document.getElementById works fine though.
Previously when developing my own modal windows I have been creating a "mask" div directly in my markup, in the CSS setting it to be display:none and then setting it to show() by jQuery when a button is clicked.
I'm sure there is a better way to do this but i'm getting a little stuck.
I tried adding the "mask" div and its content to the body using prepend() when my button is clicked but i found i then can't select any of the added elements in jQuery.
How can you select elements you have added to a page by jQuery?? Also if this is the right approach whats the best way to insert a block of html to a page??
I'm trying to update a plugin i downloaded. What i'm trying to do, is make it able to work with dinamically created objects. I'm using the live function to assing javascript events, but i need to know how to assing a plugin dynamically. This is what i have right now:
$("#txtinstruments").AutoComplete("query"); What this does is apply the AutoComplete plugin, to all the objects with id txtInstruments that are already created but, i create more objects with that id on the fly, and i need to assign the plugin to them.
When submitting a form, I would like to check the values of some fields first. These fields are dynamically generated by javascript after the page has loaded (that is, a user selected a value from a dropdown between 1 and 10, if 2 is selected, 2 inputs are generated, if 7 is selected, 7 inputs are generated etc). I think I understand that Jquery isn't aware of these items because they were created after the DOM was scanned. Is there any way I can 'refresh' jquery to make it aware of these new items?
