See if this logic helps.

<HTML>
<HEAD>
<TITLE>test</TITLE>
<script language="javascript">
function callthis()
{
inntext = new String(document.body.innerText);
inntext = inntext.replace("12345","<img src=\"next.gif\">");
document.write(inntext);

}
</script>
</HEAD>
<BODY onload="javascript:callthis();">
Replace this: 12345

</BODY>
</HTML>

innerText is IE only, try this example

PHP Code:


			
<HTML>

<HEAD>

<TITLE>test</TITLE>



<script type="text/javascript">



onload=function(){



currentContent=document.body.innerHTML

newContent='<img src="next.gif">'



document.body.innerHTML=currentContent.replace(currentContent,newContent)



}



</script>



</HEAD>

<BODY>



Replace this: 12345



</BODY>

</HTML>

Wow...it worked..but I still have one question

The code above only replaces 1 occurence of the string. Is it possible to have the script replace all occurences of the string?

If at least you use some internal tag for the text like

<span>Replace this: 12345</span>

you could use a code like this:

Code:

<script type="text/javascript">

onload = function() {

	var spanstags = document.getElementsByTagName("span");
	newContent = '<img src="next.gif">';

	for (var x = 0; x < spanstags.length; x++) {
		if (spanstags[x].innerHTML == "Replace this: 12345")
			spanstags[x].innerHTML = newContent;
	}
}

</script>

Hello, thank you for all your efforts. Here is the code I am using. As you can see I have 4 numbers of "12345". With the code I am using now only replaces the first string and does not touch the other 3. I am trying to make the script replace all 4.

Code:

<HTML> 
<HEAD> 
<TITLE>test</TITLE> 

<script type="text/javascript"> 

     onload=function(){ 

        currentContent=document.body.innerHTML 
        newContent='<img src="next.gif">' 

       document.body.innerHTML=currentContent.replace("12345",newContent) 

     } 

</script> 

</HEAD> 
<BODY> 
     Replace this: 12345 
     Replace this: 12345 
     Replace this: 12345 
     Replace this: 12345 
</BODY> 
</HTML>

You could also try

PHP Code:


			
<HTML> 

<HEAD> 

<TITLE>test</TITLE> 



<script type="text/javascript"> 



onload=function(){ 



currentContent=document.body.innerHTML



newText='<img src="next.gif">' 



oldText = new RegExp("12345", 'gi')



newContent=currentContent.replace(oldText,newText)



document.body.innerHTML=newContent





} 



</script> 



</HEAD> 

<BODY> 



Replace this: 12345 <BR><BR>

Replace this: 12345 <BR><BR>

Replace this: 12345 <BR><BR>

Replace this: 12345 <BR><BR>



</BODY> 

</HTML>

May I ask where do you guys get your javascript training from?

LukeJea · #12 12-22-2006, 10:22 AM

OK, this code below works for all the strings that I give it but it does not work for this:

Code:

:)

a smilie. I have read some books on this but cannot find a solution to this problem. If you see the code below the it does not replace

Code:

:)

. I am puzzled!

Code:

<HTML> 
<HEAD> 
<TITLE>test</TITLE> 

<script type="text/javascript"> 

onload=function(){ 

currentContent=document.body.innerHTML 

newText='<img src="next.gif">' 

oldText = new RegExp(":)", 'gi') 

newContent=currentContent.replace(oldText,newText) 

document.body.innerHTML=newContent 


} 

</script> 

</HEAD> 
<BODY> 

Replace this: 12345 <BR><BR> 
Replace this: :) <BR><BR> 
Replace this: 12345 <BR><BR> 
Replace this: :) <BR><BR> 

</BODY> 
</HTML>

Try replacing this line

oldText = new RegExp(":)", 'gi')

with this

oldText = new RegExp(":\\)", 'gi')
