Is there a way to have this run from individual links? <select name="users" onChange="showUser(this.value)"> <option value="">Select a Deer:</option> <option value="1">8002</option> <option value="2">8009</option> <option value="3">8011</option> Thanks Rich Similar TutorialsHi all, I want to reload an html page onChange event of dropdown list and retain the old values filled in the page. Plz help..... How can i change this code to do not duplicate the boxes when one option is selected in the same box as before? http://www.plpgolfandturf.com.au/rr/rrboxes_test.php Code: <script type="text/javascript">

Hi all, I'm new to javascript and am having a few issues. I have a function that I want to run with multiple onchange events. My page has several image selection buttons and I want it to preview the image when/if each one is selected. I have gotten it working for the first on the page but cannot for the remainder. Is this possible or am I wishful thinking?

If you simply want to assign multiple listeners for the same event on a single element, use element.addEventListener("change", eventHandler) instead of element.onchange = eventHandler or <element onchange="eventHandler();"></element>. I probably have gone about this all wrong since I am a complete noobe, but if someone could point me in the right direction I would be very thankful. Here is the situation. What works: I have a drop menu that is being generated by a PHP/MYSQL script, when you choose an option the onchange event is triggered and runs a function that sends the value to a php script so a graphical image can be generated and saved with a random file name. The randomly generated image name is sent back as an XML response and then image is displayed with src The Problem: I need to be able to have a function store the value from the onchange event and run again when the page refreshes. As of right now, when the page refreshes the image is gone. I have attempted to do this with cookies, but not exactly sure how I will do this and I have finally decided to ask for help. I hope my explanation is not confusing, please let me know if you need more info or if you need to see my code. Hey all, I have a little function that performs when a form item is selected. I would like to give the form items all at once and have the function perform when the user mouses over an item in the displayed list. Here is the form code: Code: <form> <select onchange="showRSS(this.value)"> <option value="">Select an RSS-feed:</option> <option value="Google">Google News</option> <option value="MSNBC">MSNBC News</option> </select> </form> thanks a bunch, Brian p.s. I tried this but it didn't work Code: <?php echo("<a href=\"http://www.msn.com\" onMouseover=\"showRSS(this.MSNBC)\">MSNBC News</a>");?>
<br />
<?php echo("<a href=\"http://www.google.com\" onMouseover=\"showRSS(this.Google)\">Google News</a>");?>

I have the following form working with on onsumbit function, but I would like to change it so that instead of having to click the purchase button to see total price, you only have to change the quanity text box input. I would welcome any help. I just can not seem to get it to work. Code: <script language="javascript" type="text/javascript">
function checkQuantity(frm) {
var succesful = false;
var numQuantity;
numQuantity = parseInt(frm.Quantity.value);
var numTotalPrice;
if (numQuantity != 0) {
numTotalPrice = numQuantity * 4;
frm.TotalPrice.value = numTotalPrice; //new String(numTotalPrice);
successful = true;
}
else {
alert("Sorry must order more than 0");
successful = false;
}
return succesful;
}
</script>
Code: <form action="" onsubmit="return checkQuantity(this)" style="width: 193px">
<table cellpadding="4" style="width:111%">
<tr>
<td class="style1">
Quanity:</td>
<td class="formInputCell">
<input name="Quantity" type="text" style="width: 55px" /></td>

I've got this listbox full of hundreds of employee names. Clicking on a name executes a function using onchange. Because of the length of the list I decided a search function would be really handy and I finally found one that works. Now the search function, when you type in the input box, scrolls the list to the first matching entry. And that's good, that's what I wanted. The problem comes in when you try to click on the name the search function found. Nothing happens ofcourse because the onchange tag in the list reacts to changes, not direct clicks. <select onchange="display.apply(this, this.value.split(','))" multiple="multiple" id="People" name="People" style="border-style: none; height:260px; width:220px; margin-bottom: 15px;"> <option selected="selected">Loading</option> </select> The list is populated by java but for testing I disabled the function that clears the "Loading" option and I set it to selected. That way the loading option is highlighted by default and the search function is free to highlight something else, then when I click on the search result it works like it's supposed to. But keeping a highlighted option at the top of the list for that sole purpose isn't very elegant, especially since if you click on it the onchange function tries to execute and generates errors. The only solution I can think of is to use java to generate another option way at the bottom of the list that has the selected attribute but I don't quite know how to do that. Does anyone have any thoughts on what I can do? Hi everybody. I'm new to both Javascript and this site, so apologies if this isn't the right way to be asking this question. Here's what I'm trying to do. I've got two dropdown boxes ('language' and 'word'). When the submit button is pressed, I want a div to show with the right word in it. I can do this fine with one dropdown box, but two has got me stumped. Any ideas would be much appreciated. S I need to highlight rows in a dropdownlist. I need to do this inside a function. I have a textbox filled with the indexes of the rows which need to be highlighted - e.g. by changing the background colour to blue. This is my function: function HighlightSelection() { var myList = document.getElementById('dropdown'); var myString = document.getElementById('textbox').value; var listitem; if (myString.length>0){ var mySplitResult = myString.split(";"); var thisInx; for (i = 0; i < mySplitResult.length; i++) { thisInx = mySplitResult[i] listitem = myList.options[thisInx]; // listitem.style.color='red'; } } } the index (thisInx) is correct - but setting its color does not work. Hi guys, i hope u can help me.

Is there a write-up or tutorial somewhere I can read and learn how to do this? Any help would be greatly appreciated, Thanks Here is the link: http://www.patagonia.com/web/us/home Hi, I am just a noob and this is my first go at javascript and html I am trying to figure out how to display info from an array in the <textarea>, I have tried a number of things nothings worked and I know it must be something simply but have tried a number of things I also have to clear the <textarea> after it displays the info mentioned above and I think I have that sorted but I also have to have the <textarea> display all signup info stored in the array when a user clicks on a button Here's the code Code: function show()
{
var myArray = new Array();
myArray[0] = document.getElementById('fullname').value; myArray[1] = document.getElementById('Address').value; myArray[2] = document.getElementById('Phone').value;
document.writeln('Thank you for signingup,' + ' ' + myArray[0] + '. Your details will be confirmed by E-mail to ' + myArray[2] );
document.writeln("<br>")
document.writeln('Details:')
document.writeln("<br>")
for (var i=0; i<myArray.length; i++)
{document.write(myArray[i] + "<br />"); }
}
Thanks Hi, I'm trying to integrate an address finder (http://www.craftyclicks.co.uk/) into my shopping cart (OsCommerce). I can get it to work but I need to add my own functionality. I'm not very experienced with JavaScript and my head has entered an infinite loop by now. The problem is that the address finder script can change the selected country in a drop-down list depending on the postcode entered by the user (using the onblur event handler). What I need it to do is to remove all other countries depending on the postcode. I can get it to remove all other countries but how do i return to the original list of countries when the postcode is changed again? Once all other counties are removed, the drop-down list will obviously only have one option left... I guess the question is also how does a function remember what it has done before, when it is called again? I have written this short test script as it is easier to work with than the craftyclicks oscommerce contribution: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

Many thanks! Martin hey guys The first dropdown has some options as : abc(a) bcd(a) cde(b) def(b) efg(c) fgh(c) The second dropdown has : a b c On selecting abc(a) in first dropdown the 'a' must get selected in second dropdown,on selecting cde(b) second dropdown must have 'b' and so on,also the second dropdown value should be disabled(grayed out) for user.Need the code in javascript.ty in advance. Hello, I am completely new to HTML/JS/CSS, therefore I know very little. I have two drop-down prompt controls with month names. One has just one value (say "July") and the other has all the months of the year ("January".."December"). The first prompt control is hidden on the page. How do I set the default selection of the second prompt control to the value present in the first prompt control? So, when the page is run, the second prompt control should automatically show "July". I was reading up on the selectedIndex property (?), but I know that it won't work because I want Index 0 to be selected in the first control and Index 6 in the second, and I expect it to change every month (next month it will be index 7 that should be automatically selected). If it matters, I am using IE8. Thanks! Hi folks. I'm working on a calculator and need to use the 'onchange' function. Basically, the user selects the year (id=taxYear) and once the year is select (default is 2008) this year will appear in 2 different lines of the page under 2 seperate ID's(ageYear & totalYear). I've looked at a few example of the function but I'm still not sure how to approach it. At the moment the year changes once I hit the 'calculate' button but the onChange would obviously offer a better alternative with the date changing once 'taxYear' is changed. here is the script; Code: //check the year
var taxYear = document.getElementById('taxYear').options[document.getElementById('taxYear').selectedIndex].value;
document.getElementById('ageYear').innerHTML = taxYear;
document.getElementById('totalYear').innerHTML = taxYear;
Here is the jsp; Code: <tr>
<td align="left" width="203" colspan=""><p> Your Tax Year: </p></td>
<td align="left" >
<s:select name="taxYear" id="taxYear" list="#{'2008':'2008', '2009':'2009'}" theme="simple" />*
</td>
</tr>
<tr>
<td align="left" width="203"><p> Age at December 31st <span id="ageYear"></span></p></td>
<td align="left" colspan="1">
<s:textfield name="age" id="age" theme="simple" cssClass="text" value="30" /> *
<div id="errorage" class="warningmessage" style="display:none">
Please enter your Age to proceed.
</div>
</td>
</tr>
<tr>
<td colspan="2" class="basicboldtext">
<br/>
The total pension contribution you can make for year <span id="totalYear"></span> is €<span id="totalTax2"></span>
<br/>
</td>
</tr>
Appreciate any help on this! Code: <input type = "text" style ='display:none;' onchange="display_data_from_server(this.value)"/> Value inside that input is cahanged from js. Is there any reason that onchange would not happen ? i mean, it does not. |
