Javascript Changing The Options Of The Second Select Box Depending On The First
Oct 17, 2007
I have two text boxes one with months in "January, Febuary..." but as not every month has the same ammount of days i need the second select box to change to instead of having options 1-30 it has 1-28 or what ever depending on what month is selected.
I'm making a <select></select> with lots of <option></option>. It contains all possible options. Because of the length of the list, I also have an <input type="text">.
This is what I wish to do:
onKeyDown I want all options that don't contain (or begin with, it doesn't matter which one) the typed letters to be removed from the <select>.
My problem is that I don't know of any code to find words and identify letters.
Not 100% sure why or how to make this work.I have 5 options in a select drop-down. Only two of them are to disable a text field. I have written it successfully to disable on one option. How would I add the second option? I have tried many different ways, and i know its something small that i am missing.Below is the code that does not work but shows the 2 options that disable my text field.
<script type="text/javascript"> function type_disable() { var qr_type = document.getElementById('qr_type');
i have a div which has an id in that i have a div which has a class name then i have a table in the second div and in that i have few links (ie. <a href=...</a>)
I've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost.When I select the first option nothing appears in the second option.
I want a text box which is only visible if the preceding drop down box has a certain option selected. Does anyone know how to do this or where I might be able to find the appropriate code?
I have two drop down box's in a form, how would I go about changing the options of the seccond one depending on what option is selected in the first one?
For example, if there's a drop down box with "a", "b" and "c" as the options, and another drop down box with "1", "2" and "3" as the options; then when you select "a" on the first drop down box the values of the seccond one changes to "a1", "a2" and "a3". This should work for all the options of the first drop down box.
In JS, how can I change the selected value of a dropdownlist(select options) I know the value of indexed value of the selected value before it is changed.
How to change style on a series of divs (with similar structure but different content) *only if* all the children are visible (that's using visibility, not display). Sample div: <div class="h"> <p class="a1">text</p> <p class="b2">more text></p> <p class="b3">text text</p> <p class="a4">text...</p> <p class="link_display_none_visibility_visible">div name</p></div> I think it needs to use contents(), but not sure about handling node numbers.
I have a form that I am using for several different pages as they are exactly the same... however at the top you must make a choice from the drop down box that then shows the appropriate fields to fill in. Can I make the drop down default to a certain option depending on which page they are coming from?
This is what I want to achieve: a fixed positioned div next to my content area where the text changes depending on the section of the content area the user is reading. Can this be achieved, and how?
I need to select browser option dynamically using javascript for handling cookies , i.e., in need select "override automatic cookie handling" checkbox dynamically. how to select this check.
While appending the option-elements to the targetselect the original option-elements disappear (exactly at step of line 13). This is unwanted behaviour.
I want <select #2> to show a list depening on what the user choose for <select #1>. The tricky part is, not allowing the user to see what <select #2> lists are. Maybe fade it out untill they pick something from <select #1>.
I'm trying to create a list that contains items which are filters for a search. The list shows 10 items (max) on the page load. if there are more than 10 it changes the class of the elements > 10 so they are hidden, and a 'show more' link is appended. Now if the user has 'unhidden' the previously hidden items and then chooses one, I want the class for all those previously hidden items to change until the user has deselected that item.
[Code]...
Is there a better, smaller way to write this? It works for what i need currently, but there are future features im planning that will not be practical checkingindividualindexes the way i've done it.
The user must bem select options in this 4 files in order, for example, he must bem select first "First Choice" next "Second Choice"... The options not be same.
I've been playing around with the following code for days already and still in the dark tunnel. Can someone tell me what's wrong with the way I've coded it?
var cell1 = row.insertCell(0); var selOpt = document.createElement('input'); selOpt.setAttribute('type', 'select'); selOpt.option = document.forms[0].Country.option; selOpt.setAttribute('name', 'AnotherCtry'); cell1.appendChild(selOpt);
<edit>What I'm trying to do is to copy the options of the Country to another select which I've allowed the users to 'add' to the current row.</edit>
I have a select and list of options. I have onkeypress event on the select input. As the user types I am trying to match the entered key strokes to the entries in the options and setting the selected value to the first match.
The problem I am facing is this: My options have 10000,0000, 10001, 1111,0001. Say I type 10, with less than one sec delay I consider them as one unit. So I try to find whether there are any entries in the options which starts with 10 and setting the value. But brower is considering the last entered key stroke , in this example 0 and setting the 0000 which is the first match.
Is there any way that I can stop the browser from doing that or any idea?
I've searched the web and every tutorial I can find says the same thing, and I am doing what they say, but it's inexplicably not working. Basically, I'm using a nested object to populate a select box using the new Option() method. Unfortunately, when I include the new Option line, it breaks the loop and does not add anything.
I have 8 pages that are very similar. The only difference is the select options with different group of names on each page. I am using a global script.Is there a way to have a central point with array of names that would write or function in the select option depending on the page.Example below
how one can show and hide a div element using a pulldown menu. i need the different selections in the pulldown menu to show hidden DIV elements on the page. this will be used in a system where i only have access to the template, so the only approach i can use is jquery. how to change it for the specific selectors i need.
