JavaScript - Change Span Based On Select Value
I am trying to change a character limit based on items changed in a drop down menu. To do this I have one function that will change the posted count based on the currently selected option and another function that is a commonly used char count with a few tweaks.
The main issue is getting the value of the currently selected option. I know that selectedIndex will return the position of the selected element rather than the actual value. I tried to code around that. I've tried every method I could find on google and nothing works. So, I may have a bigger problem on a higher level that I just don't understand. If any of you can take a look at my code and give me your thoughts I would be most appreciative. Thanks! Code:

Similar TutorialsI'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. here's the javascript code: Code:
function createOption(OptionText, OptionValue){
var temp = document.captcha_form("option");
temp.innerHTML = OptionText;
temp.value = OptionValue;
return temp;
}
function valChange(){
var firstList = document.getElementById("emailaddress");
var secondList = document.getElementById("subject");
while(secondList.hasChildNodes())
secondList.removeChild(secondList.childNodes[0]);
switch(firstList.value){
case "1":{
secondList.appendChild(createOption("Report Site Browsing Issue", Report Site Browsing Issues));
secondList.appendChild(createOption("Report Page Errors", Report Page Errors));
secondList.appendChild(createOption("Other", Other));
break;
}
case "2":{
secondList.appendChild(createOption("Report Unauthorized Game", Report Unauthorized Game));
secondList.appendChild(createOption("Report Spam", Report Spam));
secondList.appendChild(createOption("Report Harassment", Report Harassment));
secondList.appendChild(createOption("Report Illegal Activities", Report Illegal Activities));
secondList.appendChild(createOption("Request Account Removal", Request Account Removal));
break;
}
// ....
default:{
secondList.appendChild(createOption("Please select from the first list", ""));
break;
}
}
}
window.onload = valChange;
this is the form code Code: <div class="mailto_form"> <form method="POST" id="captcha_form" name="captcha_form" action="../includes/mailform.php"> <div style="padding-bottom: 1em;">Choose Recipient: <select name="emailaddress" id="emailaddress" onchange="valChange();"> <option value=""></option> <option value="1">Webmaster</option> <option value="2">Admin</option> </select> </div> <div style="padding-bottom: 1em;">Subject: <br /><select name="subject" id="subject"> </div> <div style="padding-bottom: 1em;">From: <br /><input type="text" name="email" id="email" value=""> </div> <div style="padding-bottom: 1em;">Enter the text contained in the image into the text box: <br /><img src="../includes/captcha.php" /> <br /><input type="text" name="userpass" value=""> </div> <div style="padding-bottom: 1em;">Message: <br /><textarea name="message" id="message" rows="10" cols="60"><?php echo "</tex" .

The student is supposed to select one main course as well as provide a second choice in case the first is not available. I have two dropdown select fields to capture data 1) Choice -1: 101 / 102 / 103 ( Student needs to select one - Reading the classID from classes table) 2) Choice -2: 101 / 102 / 103 ( If student selects 101 in Choice-1 then the only classes available under Choice-2 should be 102 or 103). How can I accomplish the above? Further to this there are two fields on the form where I would like to auto populate based on what they have selected in Choice-1 and Choice-2. For Example: If a parent selects choice1: 101 the child Choice1 field should autopopulate with 100. If a parent selects Choice2: 201 the child Choice2 field should autopopulate with 200 Any help would be really appreciated. Thanks Vinny Hello, I am trying to change the value of #name and #category inputs based on the value of select. A friend gave me the code below, but I can't get it to work. Thanks so much for your help Code:
<script type="text/javascript">
$('#Gift_Type').change(function(){
if ($(this).val() == 'Monthly'){
$('#name').val('Partnership')
$('#category').val('Partnership')
} else {
$('#name').val('Donation')
$('#category').val('Donations')
}
})
</script>
Code: <SELECT NAME="sub_frequency" ID="Gift_Type" onchange="OnSelectionChanged (this)"> <OPTION VALUE="1m">Monthly</OPTION> <OPTION VALUE="">One Time</OPTION> </SELECT> Code: <input type="text" id="name" name="name" value="Partnership" /> <input type="text" id="category" name="category" value="Partnership" /> Hello, I just joined the forum. I'm hoping someone could help me out or point me in the right direction. I am trying to set up a simple interaction for users. The user would be required to select a width then height from two separate drop down menus. I used this as an example to work from: http://www.w3.org/TR/WCAG20-TECHS/wo...dynselect.html The list of heights would not be available until the user selects a width.(similar to the example link above). Each width would have slightly different heights associated with it. After the user selects a width then height an image would be displayed based on that combination. So for example if the user selects 12w/30h they would see "01.jpg" if the user selects 12w/36h they would see "02.jpg". This would all be done on the same page. The user should be able to update the image by combining the different width/height options indefinitely. If anyone has a link to an example or can provide a basic structure I could build of off I would be extremely grateful, thanks. Hi, 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? Thanks Is there a way to call javascript functions based on the text between a span element? In other words if I have <span id="mySpan">Bronze</span> then it will call a javascript function but if I have <span id="mySpan">Silver</span> then it will call a different function? Thanks! Hello, I am trying to make a simple code that has a selection list (with the choice fruit or veggie). When the user chooses fruit, the second list displays the options apple, orange, banana. When the user changes their choice to veggie, the second select list then contains carrot, corn, potatoes (and the apple, orange, banana disappear). I need some advice on how to do this Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Untitled</title> </head> <body> <form name = "form1"> <fieldset> <legend>Fruit or Veggie</legend> <select name = "S1"> <option name = "fruit">Fruit </option> <option name = "veggie">Veggie</option> </select> <select name = "S2" </select> </fieldset> </form> <script language="JavaScript" type="text/javascript"> ??? </script> </body> </html> Ok so let's say I have this dropdown with a list of these items: PALCO TRIBUNA ORO And in a button on the page I want to send it one of those names, let's say I send it ORO, and through Javascript select that in the dropdown list. How is this done? Do I have to iterate through everything, and how? Thanks for any help in the subject. I have a list of thumbnails generated by Wordpress. I've been trying to piece together a script that would change the ID of the parent element based on the image inside of it I can't seem to get anywhere, does anyone have a simple solution? I need the id of the li to be "sm" or "smp" depending on the width of the image inside of it (landscape or portrait) Code: <li class="frame" id="sm">
<div class="frm" id="frame1">
<img src="image.jpg">
</div>
</li>
Hi Guys, I am looking for a script to change text on a page based on the time of day. From 9am - 5pm weekdays I would like the page to display 'Open', and outside of that window to display 'Closed'. I am using HTML & PHP. Any help would be greatly appreciated. Thanks, Matt Ok so I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load.

<option value="1">Choice A</option>
<option value="2">Choice B</option>
<option value="3">Choice C</option>
</select>
<div id="showme">
Content to show if EITHER Choice B or C is chosen. Otherwise this div should be hidden.

Can anyone lead me in the right direction? Thanks! Hi, I'm trying to build up a multi-select filter with checkboxes. I found few good scripts but I've got a problem to adapt them.. The script below can filter results based on criteria (that you can select via checkboxes). The results displayed are checked or unchecked boxes. What I want is : display results with div (for ex:<div>result1</div>) and not checkbox. How can I do that? Code: <script type="text/javascript" src="js/jquery.js.css"></script>
<script type="text/javascript">
$(function() {
$('#search input:checkbox').click(function() {
var classes = $('#search input:checkbox:checked').
map(function() { return $(this).val(); }).get().join('.');
classes = (classes ? '.' : '') + classes;
$('#results input:checkbox').attr('checked', false).
filter(classes).attr('checked', true);
});
});
</script>

Thanks for your help Hi guys I have a little problem. I have 2 textfields and I need to change a link href based on whatever is in those textfields. The link has to be in this format: Code: <a class="display" href="test.php?test1=textfield1&test2=textfield2">test</a> The reason for this is I need to launch fancybox and as far as im aware this is the best way to call it. So what im hoping is when I add type something in textfield1 this will be reflected in the url. And same for textfield2. I know this can be done easily if I submit the page but I dont want that. Hopefully some javascript/ajax can help me out? I hope im being clear but let me know if im not. Thanks so much! I'm new to coding and recently undertook the position as my school district's webmaster. We use a six day schedule where the days are labeled A-F. I want to be able to display the Today is...A graphic based on the date. I tried some scripts from other forums, but it does not appear to be working. Any suggestions? TY <code> <script language="javascript"> <!-- var picture=''; mytime=new Date(); mymonth=mytime.getMonth()+1; mydate=mytime.getDate(); if (mymonth==9 && mydate==13){picture="<img src=/images/d.gif>"; } if (mymonth==9 && mydate==14){picture="<img src=/images/e.gif width=150 height=150 alt=E>"; } if (mymonth==9 && mydate==15){picture="<img src=/images/f.gif width=150 height=150 alt=F>"; } if (mymonth==9 && mydate==16){picture="<img src=/images/A.gif width=150 height=150 alt=A>"; } if (mymonth==9 && mydate==19){picture="<img src=/images/B.gif width=150 height=150 alt=B>"; } if (mymonth==9 && mydate==20){picture="<img src=/images/c.gif width=150 height=150 alt=C>"; } //--> </script></code> thanks anyway
Hi All, I have a form that captures member registration details. In the admin section .. I would like to change the Status field of a record/s from NEW to PAYMENT DUE after 14 days from the data of submission. The status change should automatically trigger on the 15th day. So when the admin checks the list page he/she should be able to view the updated status field. Any pointers how to accomplish this? Thanks in advance. Vinny Dear all, background information: I did code a timesheet management system for my company with PHP where the user has to submit time entries and has an online form with several start and end times. The start and end times are all simple HTML select option dropdowns. I want that the first End time selection will be the next start time selection. Basically a simple dependency of the dropdown. My approach was that I want to solve this with JavaScript. In my php code I am echoing the following (in this select the end times are the values): echo "<select class='normal' name='$field_id' onChange=set_time_hour(this.value,'$field_id_js')>"; When the user changes then the end time dropdown the next field (next start time entry) should be changed accordingly. The javascript looks like this function set_time_hour(hour_value,next_field){ alert (hour_value); alert (next_field); document.getElementById(next_field).value = hour_value; } The alert calls are giving me the right values. but the document.getElementById(next_field).value = hour_value; is not working. What is wrong there? Do you have an idea? How can I change the value of a select box with Javascript? The select box values are already popoluated with PHP so I just want to select the right value. Hello I am trying to create a form which when the submit button is selected will open a new window with 1 of 4 URLs based on the the combination of data in 2 select boxes. For example: if select box 1 = a and select box 2 = a then open new window with URL 1 if select box 1 = a and select box 2 = b then open new window with URL 2 if select box 1 = b and select box 2 = a then open new window with URL 3 if select box 1 = b and select box 2 = b then open new window with URL 4 Any help would be greatly appreciated.

I want to put on the site a traffic light that would change colours based on the calendar dates where work can/can't be done. For example, if April 11th there is stuff to do, the traffic light would be green. But April 12th, there isn't work to do, it would turn red. Do you know how I would go about doing this? |
