JavaScript - Help Changing Hiddden Field
Hi,
I am writing a script which contains several check boxes, one of which selects all of the other check boxes. When check boxes are ticked the information from their values is put into a hidden field as a list and if it is un-ticked it is removed. When the one which selects all of the other check boxes is ticked I want all there values to be added to the list. I cannot get the script to fill in the hidden field when the all check box is selected. The code is, <html> <head> <title>untitled</title> <script type="text/javascript" language="javascript"> function display(box) { // get reference to form object, and to array of same-named checkboxes var temparr = new Array(), f = box.form, boxgroup = f[box.name]; // loop through it for (var i=0; i<boxgroup.length; i++) { // add the value of any checked box to next available slot in temparr if (boxgroup[i].checked) temparr[temparr.length] = boxgroup[i].value; // run the .join() method on the array (separator = ',') and output it to field f.readout.value = temparr.join(','); } } function Check(chk) { if(document.myform.Check_ctr.checked==true){ for (i = 0; i < chk.length; i++) chk[i].checked = true ; }else{ for (i = 0; i < chk.length; i++) chk[i].checked = false ; } } </script> </head> <body onLoad="document.forms[0].reset()"> <form name="myform"> <ul> <li><label><input type="checkbox" name="Check_ctr" value="yes" onClick="Check(document.myform.group)"/></label> All Africa</li> <li><label><input type="checkbox" name="group" value="01A" onclick="display(this)" onChange="display(this)"/></label> Algeria</li><li><label><input type="checkbox" name="group" value="02A" onclick="display(this)" onChange="display(this)"/></label> Angola</li><li><label><input type="checkbox" name="group" value="03A" onclick="display(this)" onChange="display(this)"/></label> Benin</li><li><label><input type="checkbox" name="group" value="04A" onclick="display(this)" onChange="display(this)"/></label> Botswana</li><li><label><input type="checkbox" name="group" value="05A" onclick="display(this)" onChange="display(this)"/></label> Burkina_Faso</li><li><label><input type="checkbox" name="group" value="06A" onclick="display(this)" onChange="display(this)"/></label> Burundi</li><li><label><input type="checkbox" name="group" value="07A" onclick="display(this)" onChange="display(this)"/></label> Cameroon</li><li><label><input type="checkbox" name="group" value="08A" onclick="display(this)" onChange="display(this)"/></label> Canary_Islands</li><li><label><input type="checkbox" name="group" value="09A" onclick="display(this)" onChange="display(this)"/></label> Cape_Verde</li><li><label><input type="checkbox" name="group" value="10A" onclick="display(this)" onChange="display(this)"/></label> Central_African_Republic</li><li><label><input type="checkbox" name="group" value="11A" onclick="display(this)" onChange="display(this)"/></label> Chad</li><li><label><input type="checkbox" name="group" value="12A" onclick="display(this)" onChange="display(this)"/></label> Comoros</li><li><label><input type="checkbox" name="group" value="13A" onclick="display(this)" onChange="display(this)"/></label> Congo</li><li><label><input type="checkbox" name="group" value="14A" onclick="display(this)" onChange="display(this)"/></label> Democratic_Republic_of_Congo</li><li><label><input type="checkbox" name="group" value="15A" onclick="display(this)" onChange="display(this)"/></label> Djibouti</li> </ul> <br><input type="hidden" name="readout" size="20"> </form> </body> </html> Can anyone help solve this? Thanks, Cs1h Similar TutorialsI'm building a template editor and need some help changing some of the variables. Part 1. Only at DEALERNAME. Must present coupon at time of write-up. Cannot be combined with any other offer. 1 coupon per customer per transaction. Expires: 00/00/00.s I need to be able to fill out two fields to change DEALERNAME and 00/00/00. I found a way to do this but it required the output to be in a field. I need it the output to look no different than before. Part 2.

Hopefully it's clear enough Right now, my div changes opacity if it's moused over qua the following code: Code: style="opacity:0.3;filter:alpha(opacity=30)" onmouseover="this.style.opacity=1;this.filters.alpha.opacity=100" onmouseout="this.style.opacity=0.3;this.filters.alpha.opacity=30 but this isn't quite optimal, cause if the user mouses out, it changes back to fade, and the user can't quite see what he's entering. So I would like the div to have opacity=1 when one of the textfields in it is active and opacity=0 when it's not. Is there a way to do that? //deafdigit Hi, Is there anyone who could help me figure out how to Change a Hidden Fields Name based on selected option. The hidden fields name is sent off and I need to change the name depending on what option they select. For if they select MyList the hidden field name needs to be SelectLists[40] or if they select testlist the hidden field name needs to be SelectLists[41]. This is probably way, way off but I've done this and it doesn't work. Any help would be greatly appreciated, thanks. <script language="JavaScript"> function changelist() { //here we assign the value of the hidden input to x x=eval(document.getElementByName("SelectLists[40]"); if(document.getElementById("SelectLists[40]").selected=true x=SelectLists[40] else(document.getElementById("SelectLists[41]").selected=true x=SelectLists[41] else(document.getElementById("SelectLists[42]").selected=true x=SelectLists[42] //now we assign the new value to the input document.getElementById("theHiddenInput").name=x; //and now we test alert(document.getElementById("theHiddenInput").name) } </script> <input type="hidden" id="theHiddenInput" name="SelectLists[40]" value="Yes"> <select class="inpBox" style="width: 287px" name='mailinglist' id="lists" onchange="changelist()"> <option value="SelectLists[40]" name="SelectLists[40]" id="SelectLists[40]">MyList</option> <option value="SelectLists[41]" name="SelectLists[41]" id="SelectLists[41]">testlist</option> <option value="SelectLists[42]" name="SelectLists[42]" id="SelectLists[42]">testlist2</option> Hi coders, I need to achieve two things upon making a selection from a drop down field: 1) Changing the background picture of a cell. 2) Changing the size of a uploaded foreground picture within the same cell.

Can anyone help me to know that a javascript which is validating a phone number accepts only digits but if the text field is left empty it should accept the entry as an empty entry.... plz share knowledge u will be more knowledgeable Hi folks. Looking to see if anyone could tell me where I'm going wrong with this script... I'm trying to have a field automatically filled with the day of the week ("Monday", "Tuesday", "Wednesday" and so on), upon the user selecting a date from the datepicker jQuery. If this isn't clear, I'll clarify further down the page. Here is the script: Code: <script type="text/javascript">
jQuery(document).ready(function($){
$('input[name="item_meta[428]"]').change(function(){
var d = $('input[name="item_meta[428]"]').val();
var n = new Date(d).getDay();
if(n == 0)
val v = 'Sunday';
else if(n == 1)
val v = 'Monday';
else if(n == 2)
val v = 'Tuesday';
else if(n == 3)
val v = 'Wednesday';
else if(n == 4)
val v = 'Thursday';
else if(n == 5)
val v = 'Friday';
else if(n == 6)
val v = 'Saturday';
$('input[name="item_meta[429]"]').val(v).change();
});
});
</script>
I'm basically trying to say, if the user selected today (15/05/2012) in the field 428 it would fill the field 429 with "Tuesday". Again, if the user selected 18/05/2012 in the field 428 then it would automatically fill field 429 with "Friday". It's being done to work in conjunction with a wordpress plugin called Formidable Pro hence the item_meta[428] etc. Any assistance would be greatly appreciated. Sam. I have a text field, call it income, that when the input is > 0 I need to dynamically show the next text box, and if it is blank hide the next text box. I would like to use onBlur but can't seem to get it to work. Can I do this? Help I have two drop down fields. When I select any value in the first drop down i want the second dropdown to automatically populate the value related to the first one. For e.g i have the first field as name and the second field as measured in. If I select 'Potato' in the first dropdown then the second drop down should populate 'kg'. Please help.
Hi Experts, I have designed an online registration system for a non profit in ASP/SQL. After the members register for classes they are automatically redirected to an invoice page with class fees. At the bottom of the page I have a Total Fees field of all the classes. The member is supposed to pay this amount to our organization. Question: We decided to do an online payment this year and would like to calculate a 2% additional amount on the Total Fees. This amount is paid to the Payment Merchant site. We cannot afford to lose the 2% since we are a non profit. Would really appreciate if someone can tell me how to 1) Add a new field under the Total field 2) And calculate the 2% additional fees and do a Grand Total. Thanks in advance. Hi all, Thanks for reading. I'm having an issue trying to accomplish the following - I have a text field (field1) already displayed on the HTML page. However, there's a link where you can add additional text fields to the page as well. When the link is clicked, the second text field is added successfully (field2), and when the link is clicked again, the third text field (field3) is added successfully. However, the third field does not add itself to the page, and the text for anything greater than a third field also isn't displayed after. This obviously means that my "fields" variable is not working right, so I'm wondering, would anyone be able to assist me to help me get that variable processing correctly? Code: <script language="javascript">
fields = 1;
function addMore() {
if (fields = 1) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field2' size='25' /> <span>Field 2.</span>";
fields = 2;
} else if (fields = 2) {
document.getElementById('addedMore').innerHTML = "<input type='text' name='field3' size='25' /> <span>Field 3.</span>";
fields = 3;
} else {
document.getElementById('addedMore').innerHTML = "Only 3 fields are allowed.";
document.form.add.disabled=true;
}
}
</script>
Here is the code in my HTML - Code: <input type="text" name="field1" size="25" /> <span>Field 1.</span> <div id="addedMore"></div> <p class="addMore"><form name="add"><a onclick="addMore()">Add another field.</a></form></p> Thank you very much. Hello, I'd like to make sure that a field is a field: Code: if ( typeof( myField ) != "field" ) {
}
This doesn't work, and I can't seem to find the answer. I can know if a field is a checkbox, for example, but I don't how to find the broader category of "input field". Hi All, My boss asked me to create an Adobe form and I'm unsure how to code it to accomplish what he is asking. I'm working with an Adobe form that has required fields. FieldA is not required but if FieldA is filled in, FieldB would then become required. What would be the ideal way to code this?

Why isn't this working? document.getElementById('main_image').src=this.href;return false; I originally had this: Code: $('#sliding_thumbs a').click(function()
{
$('#main_image').attr('src',this.href);
return false;
})
but that didn't work so I put the onclick inline and it still isn't working but I can't fathom why. I have confirmed that the #main_image is being detected correctly (by alerting the src) and that the this.href part contains the url of an image but nothing happens. There is no error and the large image doesn't load in the same window (so the return false part is working!) I have this script where people can pick a price and pick quataty. i want it to be only one price and let the person input quatity them selves, how can this be done?

Can DIV located in the MasterPage be resized depending on the screen resolution? <tr style="vertical-align: top;"><td> <div id="mainArea"> <asp:contentplaceholder id="ContentPlaceHolder1" runat="server" /> </div></td></tr> I've tried unsuccessfully - var height = screen.height; var area1 = document.getElementById('ctl00_mainArea'); if (height == 1024) { area1.setAttribute("height", "700px"); } else if (height == 864) { area1.setAttribute("height", "540px"); } Also tried area1.style.height = 700 + "px"; (no luck as well) Hi I am opening a child window with the following href. If it is a completly new window, it is opened and the focus shifts to it, ... but ... if that href has been clicked on before and the window exists, the focus stays with the parent window and does NOT shift to the child How can I make the focus shift ? here is my href: PHP Code: echo "<a href='$Ad_detail' rel=\"external\" onclick=\"window.open (this.href, '$Ad_detail', 'height=800,width=960,scrollbars'); return false\" > I guess I need a "window. ??? focus();" in there somewhere - but I don't know what the ??? should be. If you can help - many thanks I've got this script that spins an image for me but it dont stop spinning, in other words when i press startspinning with onclick it dont change it to stopspinning function it just keeps spinning, it works fine with href but not onclick. Code: function StartSpinning() {
int = setInterval( 'SpinChange()', 100 );
$( 'SpinButton' ).innerHTML = "Spinning (Click to Stop)";
$( 'SpinButton' ).onclick = "StopSpinning();";
Effect.Fade( 'turns', {duration: 0.3} );
}
function StopSpinning() {
clearInterval( int );
$( 'SpinButton' ).innerHTML = "Spin it";
$( 'SpinButton' ).onclick = "StartSpinning();";
UpdateFigure();
Effect.Appear( 'turns', {duration: 0.3} );
}
Can anyone help thanks. ok i have a script which will make a copy of the html in a div and place it into another div the problem with this it creates a duplicate element with the same id so what i want to know is can i create a new id based off old ids using a generic type script Code: function scope(e)
{
var popin = document.getElementById('popin');
popin.innerHTML = "<div class='container'>"+e.innerHTML+"</div>";
popin.style.display = "block";
}
this code is designed for taking content in a small div and placing it into a larger div to increase the viewing area so what i would need is sumthing that can look for Code: id="sum text" and maybe amend it to Code: id="sum textP" or sumthing to that extent if sum1 could point me in the right direction that would be great if my post is not clear enough just ask me to be more specific or sumthing and i will see what i can do to try and make it more clear if needed I go to a page and have this in the URL http://beta.pigskinempire.com/boxscore.asp?w=6&s=5&yr= I want to create a link on that page that when you click it it changes the URL to http://beta.pigskinempire.com/game.asp?gnum=6&gslot=5 as you can see the numbers 6 and 5 are about the only things that are similar in the substring. I will have this on multiple pages so it will be taking different numbers from the same spots of the URL and plugging them into the new URL into the correct location. Thank you very much if you can help me, I am thinking regEx will be needed but I am not very comfortable with it. Thanks again. I would like to have a code on my page that causes two or more photos to change between each other. For example, photo 1 is shown for a little while, then it switches to photo 2, etc. I would also like to switch text that goes along with the photos. I would like my layout to look like this: Photo / Text about Photo and have both switch after a little while, to the next photo and text. Hope this makes sense. Thanks in advance! |
