JQuery :: Fetching Data As The Option Is Selected?
Mar 24, 2010
I want that data against each option should be loaded as the option is selected in the combo box. As, while registering on yahoo, when we select a country all provinces of that country are loaded. (No need to click a submit button.)

what i want to do is have a selection from 'tst' trigger an input into 'choose' from the data inputted into the 'fname' and 'lname' fields.
for example, i want option '1', when selected to draw the input from 'fname' and place it into 'choose'
or i might want to select the data in 'lname' instead, so i will tie option 2 to it, so when the user selects option 2 the contents of 'lname' go into 'choose' instead.
<span style="font-family: courier new,monospace;">Hello all,</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">I've recently started with jQuery because I wanted to use it for posting details from an login form to a PHP script which should return whether the user is authenticated ox not.</span><br style="font-family: courier new,monospace;"> <br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">For this I use $.ajax, because of it's flexibility and I prefer to use it in this implementation. Reading (jQuery docs and examples) and searching a lot did not solve me on one issue: fetching the data in the callback to the global scope.
Apologies if this is a fairly simple question! I'm fetching data (from a MySQL database), and would like to show an animated loading image while the data is being downloaded, and obviously then hide it when the data is fully downloaded. I've found plenty of tutorials describing how to achieve this is the other direction (i.e. when submitting a form) but I'm not sure how to adapt these to what I want.
I have some form fields that the user can either type in or he can check a checkbox so that MySQL data for an option selected from a dynamically generated (PHP/MySQL) select menu is filled in. How can this be implemented? I have the code for the select menu.
Is there any way I could fetch data from another web page?
Things like current weather, and rate of exchange?
I would search the data for example by
-loading a web page somehow (IFRAME?) -going through all <td> tags in it and -if the <td> had a spesific text, like "weather in Fooland" then -I'd jump to the next <td> tag and take the text inside it, that hopefully had the data I was looking for.
I used an IFRAME to load a web page. It's id is called "myiframe"
var myIframe = document.getElementById("myiframe") var iframeBody = myIframe.body; var paragraphs = iframeBody.getElementsByTagName("p"); document.write(paragraphs.length); //this writes 0! the page I loaded on the IFRAME has paragraph elements right on body. Why can't I find them?
I tried using node iterator (document.createNodeIterator() ? ) too, but that didn't work at all! I tried it without the IFRAME too. If you have any guesses what it might be, please tell me. Should it work in Mozilla? Should I create the node Iterator only after the page has finished loading?
I am having trouble sending JSON data to a server. Its definitely reaching the parser.php, but I am not what to create in PHP to fetch this data. Also I am not sure my Javascript is correct.
<SCRIPT> var JSONObject = new Object; JSONObject.description = "hello"; JSONstring = JSON.stringify(JSONObject); runAjax(JSONstring);
I have my doubts if this question belongs to the javascript side since it's all good until the data from MySQL comes in, but since the javascript is the one breaking I'll take my chances.
The external js (portada.js)
Code: $(document).ready(function(){ var currentPosition = 0; var currentPosition2 = 0; var currentPosition3 = 0;

As you can see I have three divs with different slideshows (slideshow, slideshow2 and slideshow3), they have products that slide to the left. When I was testing to make sure it all looks good the sliding feature was working fine, but I lost this feature when the data was being retrieved from MySQL (at the moment on <div class="slide">).
I already know that i can change the src of an image-tag with jquery / javascript.BUT my problem is, that I try to load the new src-information from a dynamic html-sheet.So every 1 second the image src should be refreshed.
Some of my code:
<script src="jquery.js"></script> <script> var auto_refresh = setInterval(
[code]....
You can see in line 17 that it is no problem to show the fetched data from the other html-file in a div every 1 second.But I would like to change a picture dynamically.That means in detail:in the other html file stands either the value "0" or the value "1".This value should be fetched every 1 second (like the div-refresh) from the file.Then the value should be used as new src-name for the refreshing image, e.g.:fetched value = "1" => img src = "1.jpg" => [user can see a green light]fetched value = "0" => img src = "0.jpg" => [user can see a red light]How can I achieve this?
- How can I change the src name
- How can I refresh the image every 1 second with the new src name?
I am trying to make a form that collects "Number of Children" a parent has. If they select "4" from the select input, then I want to slidetoggle out the appropriate divs, one for each child.
[Code]...
I have been able to use slidetoggle in the past when attached to a button, but this one has me lost. Anyone know how to accomplish this?
I have an html drop down list. the list has an 'other' option. when the other option is selected I want a text box to pop up to the left of it for entry. I was thinking about using a hidden <div> to contain the text box. and when other is selected to unhide it. How do I unhide it when other is selected?
I am making a usermanagementsystem and working with access levels. I been trying to make a script that when it does a post request and get data in return in json to choose default selected option in a select input. I been trying for two days now all different things. This is what I got that somewhat works. Any ideas how to make it select the right option?
="theOptions1 " name ="theOptions1 "> <option> [Code]....
I want to pass it to a function that will show me the selected element: $(function() { $('#theOptions' + 2)).filterOn('#theOptions' +1, { 'a': ['a'], '1': ['1'] });}); here is a part of the function:
I'm trying set an option with a certain value to selected. I'm using this: $('#mySelect option[value="' + myValue + '"]').attr('selected', 'selected'); This has worked in another piece of code I wrote, but now IE 6 and 8 are throwing an error (in the debug bar). It's something similar to this: "The selected attribute couldn't be set. Unknown error." Anyone ever experienced something similar?
I have this validate code to validate a textbox if the user select a combo value: <script type="text/javascript"> $(document).ready(function() { $("form#2form").validate({ rules: { viaAltro: { required: "#AltraVia:checked" }}, messages: { viaAltro: { required: "Insert 'Altra via'" }}})}); </script> and this is the HTML: <select name="viaFornitura" id="viaFornitura"> <option>Seleziona la via</option> <option id="AltraVia">Altro</option> </select> <label for="viaAltro">Altra via</label> <input name="viaAltro" id="viaFornituraAltro" type="text" /> but it doesn't work.
I have a select control that has over 400<option></option>. To cut down on the user having to scroll through all 400 options I have included a text control that acts as a "Quick Index" and with each char entered into the text box the options are narowed. The problem I am having isthe once I have determined which option should be selected, how to set the option to value of "selected"
I am having trouble getting the selected option in a list of more than 20 items in sharepoint, The code below works for lists of 20 or less but not for lists of greater than 20. If any one has a snipet of code that will enable me to set a variable with the selected value from a complex dropdown it
I tried using the following code to check if the user has selected a particular option in a single select drop down has been selected, then add a class to a div to display it but it's not working and I can't figure out why. I've tried a ton of other things to but this one seems to make the most sense.
if ($("#existing-subscriber option[value='Yes']").attr('select')) { $(".information").toggleClass("show"); }
