JavaScript - Set To Ignore Errors

Hi,

Does anyone know how to make a javascript regex ignore new lines?

I have this
Code:

html = html.replace(/<!--(.*?)-->/gi, '');        // HTML comments

which matches single line comments like -
Code:

<!-- this is a comment -->

but not this -
Code:

<!--
This is a comment
on multiple lines
-->

I think the answer lies with [\s\S] but I can't get it to work

e.g. -
Code:

html = html.replace(/<!--(.*[\s\S]?)-->/gi, '');        // HTML comments

Any help will be greatly appreciated

Cheers Al

Hi

I am doing validation on a form, but instead of throwing an alert on empty fields I want to highlight those fields indicating error. if all are empty, then i would like to show only 1 generalized error
message "Pls. fill the highlighted textboxes.".
how do i do this and thanks in advance.

i get this error when ever i try to process the form:

There was a SyntaxError: Unexpected token < error due to an parsererror condition.

I've tried a couple of different scripts, and I'm getting the same result, so I know I must just be missing something. I'm very new to this, so I'm not figuring it out.

I want a text box to show the results of an increment counter. Every time I click a button, the number in the text box increments by one. I know it sounds simple, but it's not working. Help? My code is below:


Code:

   <style type = "text/css">

       .tbsize { width: 30px;
                 border: 3px;
                 padding: 10px }
    </style>


<script type="text/javascript">
 
    var i=0; 
 
    function increase() 
    { 
          ++i;
         
    }
</script> 

</head>

   <body>

    <div id = "tbsize" class = "tbsize">

    <form onsubmit = "return false" action = "">

    <table>

       <td><input type = "text" id = "addone" /></td>

       <td><input type = "submit" value = "Click to add One" 
                   onclick="increase()"></td>

    </table>
    </form>
    </div>
    </body>
    </script>

Hey guys, Working on a large project. Ive created a form that when an anchor is clicked it calls the following javascript. This code executes fine in FF and creates a new select box, input box, and delete anchor. When i attempt this code in IE 8, an error occurs. The error message below and referes to the lines in which i have used the newField array.
Code:

<script type="text/javascript">
var counter = 0;

function moreFields() {
	
		var newFields = document.getElementById('rowline').cloneNode(true);
	var insertHere = document.getElementById('inputgroup');
		var newField = newFields.childNodes;
		counter = document.getElementsByTagName('select').length;
		newField[2].name = 'item' + counter;
		counter = document.getElementsByTagName('input').length;
		newField[5].name = 'amount' + counter;
	newField[7].style.display = 'block';
	insertHere.parentNode.insertBefore(newFields,insertHere);
}
</script>

Error: Object doesn't support this property or method

Im guessing this refers to the attempt to use .name/.style . Does anyone know why this is the case or an alternative way to do this?

Thanks.

Hi. I've just finished up a web design I've been working on and of course it looks and works great in FF, but has problems in IE.

My question is, how do you see what's wrong in IE? I know how to fix the html/css but how do I see what's going wrong with the javascript and php? Is there link in IE where I can see the errors?

Thanks in advance.

I have the following code for determining 30 year amortization for fha and conventional loans:
Code:

function calc(){
var alrt="";
if (document.getElementById("down").value==""){
alrt+="Down Payment\n";
}
if (!document.getElementById("con").checked && !document.getElementById("fha").checked){
alrt+="Loan Type";
}
if (alrt!=""){
alert("You Must Fill Out the Following Fields:\n"+alrt);
}
else {
doAmb();
}
}
function doAmb(){
var pur=purchasePrice;
var down=eval(document.getElementById("down").value);
if (document.getElementById("type").selectedIndex==1){
downPay=down*.01;
downPay=downPay*pur;
}
else {
downPay=down;
}
var pay=pur-downPay;
if (document.getElementById("fha").checked){
pay=pay*(1.0225);
}
amt=getPayment(pay,360,interestRate);
writeData(pur,downPay,amt);
}
function getPayment(a,n,p) {
		var acc=0;
		var base = 1 + p/1200;
		for (i=1;i<=n;i++) 
			{ acc += Math.pow(base,-i); }
		return a/acc;
	}
function writeData(pp,dp,mp){
document.getElementById("purc").innerHTML=Math.round(pp*100)/100;
document.getElementById("mon").innerHTML=Math.round(mp*100)/100;
document.getElementById("downP").innerHTML=Math.round(dp*100)/100+" 

("+(Math.round(((dp/pp)*100)*100)/100)+"%)";
document.getElementById("loan").innerHTML=Math.round((pp-dp)*100)/100;
document.getElementById("inter").innerHTML=interestRate;
document.getElementById("ins").innerHTML=insurance;
document.getElementById("tax").innerHTML=tax;
document.getElementById("tot").innerHTML=Math.round((tax+insurance+mp)*100)/100;
document.getElementById("sptype").innerHTML=((document.getElementById("con").checked)?"Conventional":

"FHA");
document.getElementById("inputArea").style.display="none";
document.getElementById("outputArea").style.display="block";
}
function showIn(){
document.getElementById("cover").style.display="block";
document.getElementById("inputArea").style.display="block";
}

It works 100% perfectly in Firefox, but in Internet Explorer, it won't do anything.
Also, I know there may be some missing variables, those are in a separate JS file.
Edit: Also, just discovered that it works fine when used inline, but loaded from an external file, it returns an "Invalid Character" error.

If you go to: http://www.five-nine.net/index2/index.html and click on "Go Ahead what ..... info@five-nine.net" And try to submit the form, it will work in every browser except IE6, IE7, & IE9, (I don't know why IE8 is so different than the rest but w/e)... However I don't see any errors on in the JavaScript.

Does anyone know why this would happen in just those three browsers?

The validator showed up these errors on my site.
They are from a script, but I know very limited javascript to correct it, to me it seems to be OK.

1. Line 15, Column 23: character "<" is the first character of a delimiter but occurred as data

for (var i = 0; i < d.length; ++i) {

This message may appear in several cases:
* You tried to include the "<" character in your page: you should escape it as "&lt;"
* You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
* Another possibility is that you forgot to close quotes in a previous tag.


2. Error Line 15, Column 23: StartTag: invalid element name

for (var i = 0; i < d.length; ++i) {

Code:

<script type="text/javascript">
  window.onload = function() {
    if (!NiftyCheck()) {
      return;
    }
    Rounded("div#nifty", "#666", "#FFF", 30, 30);
  }
  function adjustRadius() {
    d = getElementsBySelector("div.rounded");
    for (var i = 0; i < d.length; ++i) {
      d[i].parentNode.removeChild(d[i]);
    }
    var x = document.getElementById("radiusx").value;
    var y = document.getElementById("radiusy").value;
    Rounded("div#nifty", "#666", "#FFF", x, y);
    return false;
  }
</script>

Does anyone know why these errors are coming up on the WC3?

here is the link where the problem persist
http://www.ornusweb.com/what_we_done.html

I have mixed 2 scripts the light box script(lightbox.js) and scroller script(scriptaculous.js)

the page only works with ie and in other browsers it opens as an image(light box wont work)

the errors say

1st error> uncaught script.aculo.us requires the prototype javaScript frame work >1.4.0
scriptaculous.load
(anonymous function)

2 error > uncaught typeErrorbject function object(){[native code]} has no method 'extends'
(anonymous function)

can some one help me solve these problem's

On the 'Edit Profile' page of my eCommerce Wordpress Theme (http://www.projectdisobey.com/disobeyclothing), no error message appears when I do any of the following in the ''New Password' and 'Confirm New Password' text fields:

1. 'New Password' and 'Confirm New Password' do not match.
2. 'Confirm New Password' field is left empty.
3. New password is less than 5 characters.
4. New password is exactly the same as the current password.

This is the script:

Code:

<script language="javascript" type="application/javascript">
function chk_form_pw()
{
if(document.getElementById('new_passwd').value == '')
{
alert("<?php _e(ENTER_NW_PW_JS_MSG) ?>");
document.getElementById('new_passwd').focus();
return false;
}
if(document.getElementById('new_passwd').value.length &lt; 4 )
{
alert("<?php _e(ENTER_NW_PW_MIN_JS_MSG) ?>");
document.getElementById('new_passwd').focus();
return false;
}
if(document.getElementById('cnew_passwd').value == '')
{
alert("<?php _e(ENTER_CONFIRMNW_PW_JS_MSG) ?>");
document.getElementById('cnew_passwd').focus();
return false;
}
if(document.getElementById('cnew_passwd').value.length &lt; 4 )
{
alert("<?php _e(ENTER_CONFIRMNW_PW_MIN_JS_MSG) ?>");
document.getElementById('cnew_passwd').focus();
return false;
}
if(document.getElementById('new_passwd').value != document.getElementById('cnew_passwd').value)
{
alert("<?php _e(ENTER_NW_AND_CONFIRM_PW_SAME_JS_MSG) ?>");
document.getElementById('cnew_passwd').focus();
return false;
}
}
</script>

I'd be extremely appreciative if anybody could help me fix the script so that it works as it is meant to. Javascript is not something I'm particularly familiar with...

Thanks in advance!

****ING FORUM PIECE OF ****, just wrote a whole post about my error and got taken to login when I clicked submit and the post is gone now, great, thanks for caching the tags and the title, really needed those...................flsdkjflsdkfjsd

I have a loop that originally printed out a day, in a table, that linked to a new page.
Code:

out.println("<th height=100><a href=eventPage.jsp?month="+(n+1)+"&day="+d+">" + d + "</a>");

This works fine but now I want to instead have it be a link a page thats a pop up. The code I have now is as follows

Code:

out.println("<th height=100><a href="eventPage.jsp?month="+(n+1)+"&day="+d"" onclick="popUp(this.href);return false"> + d + "</a>">);

and

Code:

<script type="text/javascript">
	function popUp(URL) {
	<!--
		window.open(URL,'width=300,height=300');
	//-->
	}
</script>

I can not seem to find where I am going wrong. Any help would be appreciated.
