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'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 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.
what would be the best way to have a hidden array of possible text directed at a textarea and then if something is not within that array "onfocus", a certain select option is chosen within that form?
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'm using Prototype and scriptaculous either, but here it is:
I have two select areas and scripts to transfer items between the two. Everything works great in FF, but in IE when an option gets removed it removes the entire select area. Has anyone ever seen something like this before?
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 a form that uses jeditable to edit-in-place several fields and select boxes. Everything is working great. Now I need to a way to add a new option to the select list. What I would like is the user select "Add New..." from the select list that would pop-up a dialog window where several fields are filled in. When the form is saved the select field is updated with the new ID and description. I use Facebox for pop-up windows to display notes when the user clicks on a topic. I know Facebox can be used to display a form. It would be ideal to use this ability when creating a new option for the select box.
If I select "Other", a text box pops up and I can type in something and hit Add Item and it will add it to the drop down box, but the selection will stay at "Other". How do I make it select the item I just added?
The field to ask where do you hear about us? I have list of options in there but when the user select "others" i want to input filed popup and want user to filed in the info.
I have a problem with the following code, when run on IE6 the value for opt_sel is null but on Mozilla or konqueror the value is the option selected (as expected). I have tried several books on the matter(and google), but they seem to indicate that what i am trying to do should work.. Code:
I'm having two Slecet Option inputs. When both are chosen i want to compare the two make sure they ar ethe same. Its for confirmation purposes.How would i get the value of a selected option. (I don't know which option is chosen, I don't know the id of the option, i dont know the value of the option. I just now the id n name of the select)
<select name="whatever"> {Loop here to output many options} </select>
If one selects Merge, then i want another form displayed with input fileds etc, but if one select Nuke then a different form will be displayed and if one selects the last option then both above forms will be displayed. Can anyone show me a script (i.e. javascript) that does just that or care for a example?
How do i select an option in a combo box? i have tried looking on the internet but dont really know what i should be searching for. what i want to happen is that when a function is called a line of code will select a specific option in a combo box. something like:
//excuse the dodgy syntax
function select_combo() { cb_1.select[3] //where option 3 will be selected (or 4 if first index is 0) }
Hi!, I want to fix via javascript the combo width to a fix value. I'd like to implement a kind of ALT / TITLE function to show the entire option when the text is longer than the combo width...
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> ---------------------
