Change The Selected Option Of SELECT Box When Value Is Known But Not Index
Jun 16, 2009
I'm assuming it's possible to change the selected option of SELECT box with JavaScript based on the value and not index, but my searches have turned up nothing that seem to address this. It may be my searching terms, but if someone knows how to do this, could you post some code samples?
I want to know the index of the option that a user clicks on in a multiple-select object (regardless of whether he selected or deselected it). This seems fairly simple but I can't seem to figure out how to do it. Does anybody know how to do this?
In the code below I want to alert the selected option of select. In Mozilla the code works (If I choose "3" alerts it). In IE alerts: nothing appear --------------------- <script> function hi() { d = document.getElementById("day").value; alert(d); } </script> <select id=day onchange="hi();"> <option>0 <option>1 <option>2 <option>3 <option>4 </select> ---------------------
I'm attempting to physically change the index order of the elements returned by a selector.For example, I'm attempting to make it so when someone clicks on a button, it swaps the index position of the element above or below it (depending on which button they press).I tried to assign it using something like $('.draggable :eq(2)').attr('index', 3)But it didn't seem to work. Is there a way to do it using jQuery, or do I have to change it within DOM itself? Or is there another way to do it?
I have a little bit of a complex script where I have a <SELECT> that is pre-loaded with options that are loaded from a database in PHP. But, when this page is loaded the <SELECT> is disabled, and is only enabled when an onChange() is triggered on another <SELECT> that is situated on the same page.
Anyway, when I enable the <SELECT> I would like to have one of the <OPTION>'s selected (instead of having a blank <SELECT>).
The line of JavaScript that I have so far (but isn't really getting me anywhere) to try to select an <OPTION> when the <SELECT> is enabled is as follows...
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() { $('#theOptions' + 2)).filterOn('#theOptions' +1, { 'a': ['a'], '1': ['1'] });}); here is a part of the function:
I have a select control that has over 400<option></option>. To cut down on the user having to scroll through all 400 options I have included a text control that acts as a "Quick Index" and with each char entered into the text box the options are narowed. The problem I am having isthe once I have determined which option should be selected, how to set the option to value of "selected"
I have a drop down with approx. 200 <option> elements, each option element has a value such as value="1", value="23", etc. Given a list of values, such as 5, 34, 43, 68, 123, how can pass those values to a function and then insert selected for each corresponding element?
I am putting together a form for people to view their profile. The form includes dropdown/select elements to get the users Occupation/Job Title, Organization Type and also their State/Province.
For the profile form, I would like whatever value the user has stored in the database to show up as the "selected" option within the select element.
When a user clicks "Add To Basket" I need some javascript to check that the size option they have selected is not "-" in the form before the actual form is submitted. my form is like so:
I tried using the following code to check if the user has selected a particular option in a single select drop down has been selected, then add a class to a div to display it but it's not working and I can't figure out why. I've tried a ton of other things to but this one seems to make the most sense.
if ($("#existing-subscriber option[value='Yes']").attr('select')) { $(".information").toggleClass("show"); }
cna anyone tell me how to use the Select = "selected" option for a simple dropdown. for example when someone chooses c it will have a code like <option selected="">c</option> (am I doing it right, well if you got a firebug some site with dropdowns offers that option) so can anyone tell me how that works. I will be using it for a purpose of just selecting parts on my array, well incorporating it
When user select, for example, option 3, how can i find which was the previously selected option? etc... I've found some javascript example that evaluate "previousIndex" property of the select element but it doesn't work at all
I am trying to display a rel of each option as they are selected into a div below it . There are several selects of classProductAvailability on the page. When one of the selects changes, I'd like the value of the rel of the selected option to display.At first it seems to work, but only if you start by changing the last pull down menu. The trouble seems to be in the"select.ProductAvailability option:selected", this needs to be written for this instance, not all of the selects of that class on the page. How do I write that, I've tried$(this+" option:selected") but it won't take.
Here's what I'm trying to do is...If you select a color, then select a shape, the color option would return to the 'selected' position.If you select a shape, then select a size, the shape option would return to the 'selected' position and so on. The end result is I would like to have only one item selected from one of the select boxes, with the other two select boxes returned to the selected position.The code is presented here.
As far as my understanding of HTML DOM aka DHTML goes, is that if the DOM structure of HTML document is changed programmatically using JavaScript in the browser, it immediately gets reflected in the page's view. For example, if following code is executed on say a click of a button
var f = document.getElementById("f1"); // f1 is id of a form var i = document.createElement("input"); i.setAttribute("type", "text"); f.appendChild(i);
the page immediately shows the new textbox under that form. But in the following code, this doesnt happen.
<form id="f1"> <select id="cars"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="fiat">Fiat</option> <option value="audi">Audi</option> </select> </form> <script> // Gets executed say on click of some button var c = document.getElementById("cars"); c.options[1].setAttribute("selected", "selected"); // doesnt work c.options[1].selected = true; // works </script>
the option in combo box remains same. I checked in Firebug that the attribute is added properly. Using the selected attribute works. Why so?
I'm having some trouble with what seems to be a fairly simple issue: I have a <select> field with a few options inside of it. The idea is that a user can select an option in this dropdown and, dependent on what they choose, the output in another div with change.
The form: <form class="formStyle"> <fieldset> <label for="soFormStyle">style:</label> <select name="soFormStyle" id="soFormStyle">
[Code]....
So, this JQuery only works if the option is preselected (if I select and reload the page). I thought I was on the right track, but I just can't get it working as I intended. Again, the idea is that a user selects "Page Curl" or "Logo", and the image in the preview pane changes according to their selection.
I don't know if this is something you could do without JavaScript, but anyways... I want to make a drop down menu that changes a form based on the option, like if I chose Option1, it would show Form1 and so on.
I have a select dropdown with several options. The user selects an option and fills out the following few fields. If the user then changes his mind and changes the option in the dropdown, I want all the fields - or just the ones already filled out - to be cleared.
Note: reset() of the form is not an option as there are other things going on (hide/display of fields based on the dropdown option selected).
I know this will have been covered but search isn't working for me at the moment. Easy one for people who know JS anyway, I'm sure: I have a SELECT box that precedes a text input, however, when a particular option is selected (the value of which is "BETWEEN") I need a hidden SPAN to become visible. It is hidden as default with "visibility:hidden;" so I need to just change it to "visibility:visible;" if memory serves. Anyway, likewise, if it is already visible, I need it to be both hidden and have the input in that span have an empty value. Any tips? I need to apply this to many rows in a table, so a function that I can call with the span and input IDs would be best I reckon.
