JavaScript - Js Function Problem
Hi,
In ASP.NET intranet web page have user input. Have 5 check boxes with two attending text boxes for each. The default value for the text boxes is zero and the text boxes are disabled for input. When the user checks a check box the two corresponding text boxes become enabled for input. Have two command buttons - Submit for database posting and Cancel. I set the Cancel button with a js window.confirm, uncheck the check boxes, and reset any input values in the text boxes back to zero. When I tested the code the checked check boxes were unchecked and the first text box holding user input was reset to zero value. However, the other text boxes containing user input values were not reset to zero. I altered the sequence of the code - for example - list the check box then its text boxes and so on. I tried listing the text boxes first then the check boxes. These did not resolve the problem - I was thinking linear execution of the code. Any suggestions to rememdy this? This is the js function: function Empty() { var res=window.confirm("Please confirm cancellation-your input will be cleared"); if(res==true) { document.getElementById("chkDVTT").value=""; document.getElementById("chkLM").value=""; document.getElementById("chkVMB").value=""; document.getElementById("chkVEB").value=""; document.getElementById("chkVUB").value=""; document.getElementById("txtDVTTRegHrs").value="0"; document.getElementById("txtDVTTOTHrs").value="0"; document.getElementById("txtBRLMRegHrs").value="0"; document.getElementById("txtBrLMOTHrs").value="0"; document.getElementById("txtVMBRegHrs").value="0"; document.getElementById("txtVMBOTHrs").value="0"; document.getElementById("txtVEBRegHrs").value="0"; document.getElementById("txtVEBOTHrs").value="0"; document.getElementById("txtVUBRegHrs").value="0"; document.getElementById("txtVUBOTHrs").value="0"; } } Thanks, John Similar Tutorials<p> <script type="text/javascript">// <![CDATA[ var metrics = { "mm" : 1, "cm" : 10, "m" : 1000, "inch" : 25.4, "foot" : 304.8 }; function convert(num, dec){ var val = document.getElementById("fromVal").value; if(isNaN(val)){ return } function roundNumber(num, dec) { var result = Math.round( Math.round( num * Math.pow( 10, dec + 1 ) ) / Math.pow( 10, 1 ) ) / Math.pow(10,dec); return result; } document.getElementById("toVal").value = val * metrics[document.getElementById("fromSystem").value]/ metrics[document.getElementById("toSystem").value]; } var interval = null; function watchChanges(){ interval == null ? setInterval("convert()", 500) : clearInterval(interval); } // ]]></script> </p> <table> <tbody> <tr> <td><input id="fromVal" style="width: 100px;" onfocus="watchChanges()" onblur="watchChanges()" type="text" /><select id="fromSystem" onchange="convert()"> <option value="mm">millimeters</option> <option selected="selected" value="cm">centimeters</option> <option value="m">meters</option> <option value="foot">feet</option> <option value="inch">inches</option> </select></td> </tr> <tr> <td colspan="1" align="center">=</td> </tr> <tr> <td><input id="toVal" style="width: 100px;" type="text" disabled="disabled" /><select id="toSystem" onchange="convert()"> <option value="mm">millimeters</option> <option value="cm">centimeters</option> <option value="m">meters</option> <option selected="selected" value="foot">feet</option> <option value="inch">inches</option> </select></td> Hello, I'm working on my little grabber and now I want to try something in javascript without success, so here my javascript code: PHP Code: //begin ajax grabber function validateGrabber(b_on_submit){ if(document.grabber.keywords.value == '' || document.grabber.keywords.value == 'search'){ alert('You did not enter a search term.

i need to fix this function or a different (external is better )with the same results thanxz Hi. Firstly, i apologise for this being a google maps related question but the problem is a regular javascript question i believe, and it's really frustrating me. As i'm sure you're aware that with the maps you can click on a red 'marker' and make an info box pop up. I'm trying to do this with a text link outside of the map. My problem is calling that script via the text link. i really can't see what i'm doing wrong; my html link Code: <a href="javascript;" onmouseover="marker.openInfoWindowHtml();">test</a> and the javascript from the map Code: GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml();
});
I'm sure it's something simple but i've been trying variations for hours and I can't get my head around it. Anyone with any ideas would be an absolute star. Cheers, Pat. What I want to do is have a two-dimension array where some of the elements point to the value in another element. I have done this successfully in PHP using referfences (=&) and now I want to do it in JavaScript. My JS skills are limited but I found this post explaining how it can be done - http://stackoverflow.com/a/1687183 Here's the code from that - Code: Function.prototype.toString = function() {
return this();
}
var x = 1;
var y = function() { return x }
x++;
alert(y); // prints 2
It looks like it will do what I need to do. However, I want to use a two-dimension array, and if I try this it doesn't work - Code: for (var a = 2; a <= 5; a++)
for (var b = 1; b < a; b++)
matrix[a][b] = function() { return (matrix[b][a]) };
matrix is the two-dimension array which is alreay set up with some values. The two for loops are structured to fill in the rest of the values as references to existing values (it's a 5 x 5 array). The problem is coming from function() { return (matrix[b][a]) } because instead of the values for a and b being used in the creation of the anonymous function the actual variable names are used instead. Then later when I attempt to read one of the values setup by this it is "undefined" because the anonymous function is tries to return matrix[a][b] rather than matrix[4][2]. Can anyone help? Thanks! Hi guys I kinda needed help on jQuery/ javascript.. Here's the test page.. http://development.andrewfopalan.com/devpage/test.html# what I'm trying to do is like this.. http://trailers.apple.com/trailers/s...bandofmisfits/ the movie box... so far, I have made the cosmetics.. but the thing I was going to ask was.. when you click on the down arrow.. a popup dropdown list is going to show.. the problem is I am copying the same effect as the one with apple.. when you click outside of the popup dropdown list, the dropdown list should be fading out... but it wouldnt...

I'm not gonna lie i have no clue as too what i'm doing Hello I would like to know how this is not functional. surely passing the function to another function would work so I can use the same variables without having to write it out again.

Hi, I am inserting fields from a .csv file into database using integration engine(rhapsody) there is a javascript filter where I am trying to catch rows that have extra commas in the field text. Tried using the following code but the rows with extra commas just error and don't get inserted. Code: // Loop through all the input messages
for (var i = 0; i < input.length; i++) {
var next = output.append(input[i]);
// Get the body of the current input message
var body = input[i].text;
// Set the body
next.text = body;
var name =next.getProperty("BaseFilename");
var fields = name;
var fieldsList = fields.split(/\s*,\s*/);
if (fieldsList.length >= 10)
{
name="error"+i;
input.setProperty("BaseFilename", name );
}
}
Hi, I am learning javascript from a book ("Javascript and JQuery Missing Manual") and one example there sets my head spinning and I can't understand how the script works. I'd be very grateful if someone could write a few words about the aspect I don't understand. Basically it is line seven I don't understand. How is the word question tied to the items in the questions array. I understand the 0 and 1 on line eight and nine and why they focus on the first and second item in the sub-array, but still, how can the word question point to the relevant item in the questions array? Code: var score = 0;
var questions = [
['How many moons does Earth have?', 1],
['How many moons does Saturn have?', 31],
['How many moons does Venus have?', 0]
];
function askQuestion(question) {
var answer = prompt(question[0], '');
if (answer == question[1]) {
alert('Correct!');
score++;
} else {
alert('Sorry. The correct answer is ' + question[1]);
}
}
for (i=0; i<questions.length; i++) {
askQuestion(questions[i]);
}
I guess it is because it is 2am and had a few beers but i cannot get this to work and i know its pretty simple to do - see the code below: Code: {if ""|fn_needs_image_verification == true}
{assign var="is" value="Image_verification"|fn_get_settings}
<p{if $align} class="{$align}"{/if}>{$lang.image_verification_body}</p>
{assign var="id_uniqid" value=$id|uniqid}
{literal}
<script language="javascript" type="text/javascript">
function reloadCaptcha() {
captcha = document.getElementById("captureURLID").src;
return captcha += 'reload';
}
</script>
{/literal}
{if $sidebox}
<p><img id="verification_image_{$id}" class="image-captcha valign" src="{"image.captcha?verification_id=`$SESS_ID`:`$id`&`$id_uniqid`&"|fn_url:'C':'rel':'&'}" alt="" onclick="this.src += 'reload' ;" width="{$is.width}" height="{$is.height}" /></p>
{/if}
<p><input class="captcha-input-text valign" type="text" name="verification_answer" value= "" autocomplete="off" />
{if !$sidebox}
<img id="verification_image_{$id} captureURLID" class="image-captcha valign" src="{"image.captcha?verification_id=`$SESS_ID`:`$id`&`$id_uniqid`&"|fn_url:'C':'rel':'&'}" alt="" onclick="this.src += 'reload' ;" width="{$is.width}" height="{$is.height}" />
{/if}
<img src="{$images_dir}/icons/icon_reload.png" height="25" width="25" alt="Reload Captcha Image" onclick="reloadCaptcha();" class="valign image-captcha" /></p>
{/if}
now the following works totally fine, when you click the captcha code changes..... "onclick="this.src += 'reload'" you will notice i have added a custom reload button image below this with a onclick calling a custom function "reloadCaptcha(); which i want to reload the captcha image above it - however it is not working, i have done the function so it grabs the src from the element ID, i have added 2 ID's to the IMG but cannot remember if you can have multiple IDs or not which if not could be causing the problem but not 100% sure how to include the smarty code for the generated ID on that image. Any ideas on the code above from having a quick glimps? as the code stands i get the error: Error: captureURL is null Many Thanks ok im having a bit of problem with this. code : <input type="hidden" value="&nsbp;" name="b1r1c1"> (insde a table} <td></script>function ba1r1c1() { document.write(b1r1c1.value); }</script></td> (later on) <script> ba1r1c1(); </script> Whats happening is its not writing the space inside the cell but somewhere else on the page but i dont know why. The table is inside <div> tags if that helps. any help apreciated. Thanks Hello, As the title states, I have a problem with a function that hides content contained in DIV tags. Here is the function: Code: <script language="JavaScript">
function toggle(id) {
var state = document.getElementById(id).style.display;
if (state == 'block') {
document.getElementById(id).style.display = 'none';
} else {
document.getElementById(id).style.display = 'block';
}
}
</script>
Now, the function itself works perfectly. The problem that I have is that it doesn't work the way I need it to. I have 4 links that need to show the content of a corresponding DIV section. When a link is clicked I need it to check the state of the other 3 DIVs and hide any that are open, then display the content for the link that was clicked. I can tell from the function I am using that it already checks the state of any 1 given DIV then acts accordingly (shows if hidden, hides if shown). While this works, I am having a hard time figuring out how to modify it to suit my needs. I am completely new to JavaScript but I do know some VB so I am not a stranger to programming in general. What I would like is some direction on how to modify the above function to handle the logic I need. I would prefer instruction on how I should go about it so I can get some experience, but any help is appreciated. Thanks! PS, I am setting the display property of all 4 DIVs to NONE by default via embedded CSS. Hi, i want a page with rotation of images, with fading. I'm trying with two images, but i see only the first image. Firebug console give me this error: Quote: $ is not defined: eval ('div =$("#focus_'+categoria+'")'); This is the entire code: Code: <script type="text/javascript">

Hello was following a tutorial online from bucky. and created a new example with different variables and such. My code in my eyes looks absolutely fine but however it does not display can anyone spot the problem?

The main problem is in "onclick" in <div> element. This script generates: <div id="1" style="position: absolute; top: 100px; left:100px;" onclick="undefined;">device</div> Hello everybody I need your help in this problem At first, this is the code used HTML Code PHP Code: <input type="text" onfocus="fadeIn(this)" /><div class="box" style="opacity: 0.0"></div><br /> <input type="text" onfocus="fadeIn(this)" /><div class="box" style="opacity: 0.0"></div> JavaScript Code PHP Code: function fadeIn(elem){ element = elem.nextSibling; elemOpacity = element.style.opacity; element.innerHTML = elemOpacity; if (elemOpacity < 1.0) element.style.opacity = parseFloat(elemOpacity) + 0.1; timeIn = setTimeout(fadeIn, 100); } I have used the opacity property to make fading element like fadeIn() function in jquery , and i have used onfocus event to execute the code . Problem exists in setTimeout function, this function Does not work But the code works without this function What is the cause of the problem , Please help me Hi, firstly I apologise if the title of this thread isn't quite accurate. I'm sure you've all heard it before but I am a complete newbie to Javascript so again: apologies if this is boring and tiresome to even read, let alone help with! I have been asked to make some changes to a form that uses Javascript for the form validation. There is a 'function' that contains the variables of the various form fields and then further code to raise 'alerts' if one of the fields on the form hasn't been filled in. My problem is that for some reason I am unable to add an extra variable to this code after the field of 'County' (this will hopefully make sense when you see the code / link...) and I am stumped as to why. I am able to add variables for all of the other required fields except for 'Postcode' after 'County'. This is the case for both forms. The link is he http://samdelara.co.uk/previews/banq...ation-form.htm and the code I am trying edit is below: function checkAvailibility() { // re-calculate... calculate (); if ( isName() && isAddress1() && isTown() && isCounty() && isPostcode() && isYourEmail() && isFuncDate() && somethingToQuoteFor() && isYourEmailValid() ) { document.ordersummary.emailQuote.value = "No"; setValue(); return true; } else { return false; } } function isName() { if (document.ordersummary.Name.value=="") { alert ("\n Please Enter Your Name") document.ordersummary.Name.focus(); return false; } return true; } function isAddress1() { if (document.ordersummary.Address1.value=="") { alert ("\n Please Enter Your Address") document.ordersummary.Address1.focus(); return false; } return true; } function isTown() { if (document.ordersummary.Town.value=="") { alert ("\n Please Enter Your Town") document.ordersummary.Town.focus(); return false; } return true; } function isCounty() { if (document.ordersummary.County.value=="") { alert ("\n Please Enter Your County") document.ordersummary.County.focus(); return false; } return true; } function isPostcode() { if (document.ordersummary.Postcode.value=="") { alert ("\n Please Enter Your Postcode") document.ordersummary.Postcode.focus(); return false; } return true; } function isYourEmail() { if (document.ordersummary.YourEmail.value=="") { alert ("\n Please Enter Your Email") document.ordersummary.YourEmail.focus(); return false; } return true; } function isFuncDate() { if (document.ordersummary.FuncDate.value=="") { alert ("\n Please Enter Your Function Date") document.ordersummary.FuncDate.focus(); return false; } return true; } function isemailonly() { if (document.ordersummary.emailonly.value=="") { alert ("\n Please Enter Your Email Address") document.ordersummary.emailonly.focus(); return false; } return true; } Any help with this would be very much appreciated and once again, I apologise for my distinct lack of knowledge in this area!
