JavaScript - If End User Enters Commas, Validation Will Replace Comma

Hi,

I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it?

intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\'

I am posting my javascript function he

<a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a>


function OpenDocPreview(url, docname) {
alert('message from search base : ' + url + ' ' + docname);
}

thank you,

Does anyone know of a good library/function that will add the commas to a number automatically as the number is entered into a field?

Is there a built in function to format a number to 2 decimal places and to add commas like below.

2,222.33
30,033.98
1,222,345,99

I frequent a site that involves typing huge numbers. And I'm thinking of making a userscript that automatically adds commas as I type numbers on all the input boxes. There are multiple input boxes and it has two types: First input type has similar name ; Second input type has similar class.

Here's an example of a page:
Code:

<input type="text" value="0" name="buy_price"><br/>
<input type="text" value="0" name="buy_price"><br/>
<input type="text" value="0" name="buy_price"><br/>
<br/>
<input type="text" value="0" class="money-input"><br/>
<input type="text" value="0" class="money-input"><br/>
<input type="text" value="0" class="money-input">

My code so far. But it doesn't seem to work. The main function was taken from here.
Code:

function add_commas(number){

	//remove any existing commas...
	number=number.replace(/,/g, "");
	//start putting in new commas...
	number = '' + number;
	if (number.length > 3) {
		var mod = number.length % 3;
		var output = (mod > 0 ? (number.substring(0,mod)) : '');
		for (i=0 ; i < Math.floor(number.length / 3); i++) {
			if ((mod == 0) && (i == 0))
				output += number.substring(mod+ 3 * i, mod + 3 * i + 3);
			else
				output+= ',' + number.substring(mod + 3 * i, mod + 3 * i + 3);
		}
		return (output);
	}
	else return number;
}

function addattribute() {

	//adds onkeyup and removes zero of first input type
	document.getElementsByName("buy_price")[0].setAttribute("onkeyup", "this.value=add_commas(this.value);"); 
	document.getElementsByName("buy_price")[0].removeAttribute('value');

	//adds onkeyup and removes zero of second input type
	document.getElementsByClassName("money-input")[0].setAttribute("onkeyup", "this.value=add_commas(this.value);"); 
	document.getElementsByClassName("money-input")[0].removeAttribute('value');
}

window.onload = addattribute;

EDIT: I believe the function function add_commas(number) works. But the problem is I need to find a way to add
onkeyup="this.value=add_commas(this.value);" to the input boxes mentioned.

EDIT #2: Well I guess I'm back to 0.The function function add_commas(number) seems to only work if it's on the actual html file inside <script> tags. But once you separate it and apply it as a userscript, it doesn't seem to function.

Hello:
I have an expression validating email addresses but it seems there is a loophole. If a user enters a comma this is accepted. Can anyone tell me how i can modify the following to disallow commas?

validRegExp = /^[^@]+@[^@]+.[a-z]{2,}$/i;
strEmail = document.form1.df_email1.value;

if (strEmail.search(validRegExp) == -1) {
alert("A valid e-mail address is required.");
document.form1.df_email1.focus();
return false;
}

Hello my first post.
I have a function that insert commas via onclick or onblur.

Code:

function addCommas(nStr)
{
	nStr += '';
	x = nStr.split('.');
	x1 = x[0];
	x2 = x.length > 1 ? '.' + x[1] : '';
	var rgx = /(\d+)(\d{3})/;
	while (rgx.test(x1)) {
		x1 = x1.replace(rgx, '$1' + ',' + '$2');
	}
	return x1 + x2;
}

I also am using code from this link, where I can specify what parameters to allow the user to enter only positive/negative, decimals values and restricting characters that are not allowed.
http://www.mredkj.com/tutorials/validate2.html

I am having a hard time to incorporate the addCommas function into the link above.

Does anyone have an example that I can look at where I can have commas added to a value dynamically while typing?
e.g. if I type 1000 after that last 0 keystroke, it turns the value into 1,000. If I add 3 more zeros it turns it into 1,000,000. In the same vain if I subtract a 0 from the 1,000,000 the value is 100,000 instead.

I appreciate any assistance in advance.

i am trying to make an online graphing calculator with javascript. dont ask how because i dont know. but there is an annoying error in a do...while loop. although it should break out of the loop when the |'s (absolute value signs) are replaced with Math.abs( and ). here is the code.

Code:

var initec = function(){
    var rg = {
    }
    ;
    rg.matc = false;
    rg.i = 0;
    rg.change = function(equ){
        if (typeof(equ) != "string"){
            alert('Equation must be a string');
            return;
        }
         alert("starting equation: "+ equ);
        rg.i = 0;
        do{
            rg.matc = equ.match(/\|/);
            if(rg.i === 0){
                equ.replace(/\|/, " Math.abs(");
                rg.i = 1;
                alert("1 "+equ);
            }
            else {
                equ.replace(/\|/, " ) ");
                rg.i = 0;
                alert("0 "+equ);
            }
        }while(rg.matc) 
        alert("finished equation: " + equ);
    }
return rg;
}

rg=initec();
rg.change("|8/x+7|-2");

the last 2 lines and the alerts are for debugging. as you can see, it is not finished. but still, it should work.

I have a gridview that displays client data. The first column on each row for the gridview is a checkbox. The second column on the gridview is client name and the third column is account holder. The user can select checkboxes (on multiple rows) to modify data (account holder).

I want to add clientName column value in a comma delimited string to a hiddenfield on my page.
How do I do that using javascript, as I do not want to use postback and looping through each row on the grid to get the checkbox status. When a checkbox is checked, it should append the hiddenfield value.

I am a newb on javascript. Please review my javascript code and suggest corrections. I am getting the hiddenfield value as blank no matter what checkboxes are checked. I also know that my code is not targeting the correct row to get ClientName (row where checkbox is checked).

Any help is highly appreciated.

Thanks.
Code:

function RowClick(CheckBox) 
        {
            var BaseControl = document.getElementById('<%= this.myGrid.ClientID %>');
            var TargetControl = document.getElementById('MyHiddenField');
            for (var i = 0; i < BaseControl.rows.count; i++)
            {
                var rowElem = BaseControl.rows[i];
                for (var x = 0; x < rowElem.cells.count; x++) 
                {
                    var ClientName = rowElem.cells[1];
                    if (CheckBox.checked) TargetControl.Text += "," + Case_Id;
                }
            }
        }

Hi there!

I'm trying to retrieve the integer value in the string: #10
So I'm using the JS Split function

Code:

<script type="text/javascript">

var str="#10";
document.write(str.split("#"));

</script>

Is the code I'm using, but I keep getting a comma before my result..
in this case, my result is ",10"

What should I do?
Thanks!

Kind Regards
Matthew

P.S. I know that it's an array, but is there still anyway for me to get rid of the comma?

Hey all.

I have a simple validation I need to do. I need to just make sure that a Checkbox is checked, and that a Text field has content. Sounds simple but I cannot find any thing that has a check and a text field.

Here what I have. Can I modify this script to do this? A Checkbox MUST be checked and Text field MUST be filled out. This currently does the text field fine, but no Checkbox obviously.

How can I add a checkbox validation to this?

Thats it. Any help is appreciated.

Code:

<script type="text/javascript">

var textFields = ["digsig"]; 

function validateForm( )
{
    var oops = ""; // must initialize this!
    var form = document.sig;

        for ( var t = 0; t < textFields.length; ++t )
        {
              var field = form[textFields[t]];
              var value = field.value.replace(/^\s+/,"").replace(/\s+$/,""); // trim the input
              if ( value.length < 1 ) 
              {
                    oops += "You MUST enter your Digital Signature";
              }
        }
        if ( oops != "" )
        {
            alert("ERROR:" + oops);
            return false;
        }
    }


}

</script>

Hello all, new here Seems like a very nice place to be apart of.

I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it.

The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem.

I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs.

<problem>
I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location.
<problem>

I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.

Any pointers in the right direction or solutions to my problem would be greatly appreciated.

Thanks! Hopefully it is not to hard huh

If there is anything anyone needs, the code pasted here, or anything else please let me know. Thanks again!

First of all, I don't want to replace text in a form, or on click.

I'm writing up a design document in HTML, and I need an area to display code.
The < and > tags won't show up, obviously, but to make it easier on the programmer, I don't want him to have to manually put in &lt; and &gt; for each time it shows up.

I am aware that JavaScript has a replace function, but I am not familiar with JavaScript quite yet.

Is there a way to have JavaScript find the < and > in a certain div, and replace it with &lt; and &gt; on load?

I would appreciate your help so much, Its been frustrating me.

Hi

I'm looking for a very simple script to replace one div with another. I've found a few but they seem overly complicated with features I don't need. I simply want to be able to click on a div and for it to be replaced with another div previously hidden. If someone could suggest a solution or point me in the right direction I'd really appreciate it.

Thanks
