It is not possible to disallow people from saving from IE. Anything which is rendered to the browser can be saved by user.

(choose file,save or save as from menu of IE)

It's a bug, confirmed by Microsoft. See here[^]. Anyways, it works with FireFox.

Can I compile browser JScript into a IL byte code using JScript.NET?

If so once my code is in compiled form can I still use it like I would interpreted script from a web page?

Would my users have to download any kind of active X control or anything? Would everything be OK so long as they had IE 6 or would they need to download the .NET dll's or do they dome with IE 6?

JScript.NET is targeted at server side coding. Any IL will need the .NET Framework to be installed on the machine on which it executes.

I cannot for the life of me find an example of JScript/javascript regex which would strip only a given tag.

Can someone give me the regex required to strip only a single tag?

I cannot just do a simple find for P tags or something and remove them, becuase each element may have attributes as well.

So

<b>test</b>
<b style="font-size: 12pt">test</b>

Must output:
test

In a perfect world I would like a routine similar to PHP strip_tags() where I could specifiy which tags I wanted removed.

strip_tags(org_text, tags_not_2_keep);

called as:

strip_tags("some text", "p, b, i, iframe");

The above function would strip all tags, BUT p, b, i, iframe

If anyone knows of a javascript function which does this...I would really appreciate you showing me it.

I have found the following but it needs a bit of tweaking:

String.prototype.strip_tags = function() {
  return this.replace(/<\/?[a-z]+>/gi, '');
}

How do I print my voice mail?

Try something like this:

JavaScript

/// <summary>
/// Strip HTML tags from a string.
/// </summary>
/// <param name="value">The string to parse</param>
/// <param name="exclude">
/// True to keep specified tags; 
/// False to strip only the specified tags;
/// </param>
/// <param name="tagsToExclude">The tags to keep / strip</param>
/// <returns>The parsed value</returns>
function stripTags(value, exclude, tagsToExclude)
{
    if ("string" != typeof(value) || 0 == value.length) return "";
    if ("boolean" != typeof(exclude)) exclude = true;
    
    var arrTags = null;
    var tagCount = 0;
    
    switch(typeof(tagsToExclude))
    {
        case "object":
            // Passed an array of tags
            if (Array == tagsToExclude.constructor)
            {
                tagCount = tagsToExclude.length;
                if (0 == tagCount)
                {
                    // Possibly a sparse array?
                    arrTags = new Array();
                    for(var key in tagsToExclude)
                    {
                        arrTags.push(tagsToExclude[key]);
                        tagCount++;

I want to know how to detect when a button on the keyboard is pressed and what button.I am specifically looking for a way to tell when the up arrow,down arrow,left arrrow,right arrow is pressed.thanx.

onkeydown onkeyup onkeypress

How do I print my voice mail?

In those events, you would use the window.event.keyCode or keyChar properties to see which key was pressed.

Does anyone know how to detect whats happening in a frame?
Such as when a link is clicked the page is refreshed and even its source code?If you do know please let me know.

I imagine it's possible.

If you can get the FRAMEs window object then you could get it's document object and from there you can capture just about any event.

Hi there guys,

Have created an OCX for use in a web page, and used Visual Studio Installer to package it into bith .msi and .cab formats. In the page that it is to be used in, I am using an <OBJECT> tag with the CODEBASE attribute set to point to the .CAB (Have also tried with the MSI and same problem...." . I am getting the message telling me that need to download and install it, but after clicking Yes, nothing seems to happen.

Is there a step that I am missing, or could anyone point me to a tutorial on this and Digital Signatures?

It sounds like the CAB file wasn't found in your codebase path, or the version in your object tag is greater than the version of the control in the cab. Your tag should look something like this:

<OBJECT  classid="CLSID:MYBIGGUID"<br />
	codebase=../BIN/MYCONTROL.cab#Version=1,0,0,21"<br />
	id="rtfChartViewer"<br />
	style="height:100%;LEFT:0px;TOP:0px;WIDTH:100%;" VIEWASTEXT><br />
</OBJECT>

Hi
i need an special Regular Expression, but i don't know how to create them. Maybe one of you can help me.

Sitation:

$query = "SELECT * FROM table WHERE att = '$d-Name$';

i have to replace "$d-Name$" with an value - like this:

$query = "SELECT * FROM table WHERE att = 'jakob'

thx 4 any help
jazz

Do you really need a regular expression for this? I mean, it's a simple string search replace so using a regex will be a bit of an overkill.

What language are you using?

I just discovered that <HTML> tag will be automatically removed from text entered in a <textarea> when <textarea> loses, then regain input focus. How can I get around it?

Example: Entering this into <textarea>...

<HTML><BODY>login<INPUT name=login><BR>password <INPUT name=login></BODY></HTML>

will get trimmed down to:

login<INPUT name=login> <BR>password <INPUT name=login>

Thanks!

A textarea won't AFAIK remove anything....

However htmlarea which replaces an textarea does remove html and body tags. See htmlarea (here on CP) for possible solutions.

Hi,

I'm developing an application that takes credit cards. I do not want to go back to the server when the client swipes the card to break the mag-stripe data apart, so I would like to do this client side using JavaScript.

I can write the JavaScript code, I just don't know how to code the input statement in HTML to call my script on a text change of a textbox.

Thanks,

Glenn

Check your form elements inside onsubmit

Try this code. This will put a text box on the browser and when you change the text and step back on to browser, will call teh function 'yourfunction()'

This is my code for calculating Variance between two dates

function presentDate(startDate, endDate) {<br />
    var ierr = 1 ;<br />
    <br />
   // Verify whether the user wants to return only whole<br />
   // intervals or intervals rounded to the nearest number <br />
   // of interval.<br />

   // Verify that the user entered something in the<br />
   // Start Date input box.<br />
    if(startDate != '') {<br />
        if(!isNaN(Date.parse( startDate ))) {<br />
            var s = new Date(Date.parse(startDate)) ;<br />
            ierr = 0 ;<br />

    return iOut ;<br />
}

Now again, I need to find the variance between these two dates excluding the non-working days i.e Thirsday and Friday.

Help kindly appreciated.
