How to get an exact match whilst searching inside a string.

[Neil Gilbert]

Ok i am fudging a legacy CRM system and i need to hide a button on the script using client side javascript.

I am trying to hide a button on the screen based on the URL containing the word SendEmail by looking inside the HREF tag and if there is a match... hide it!

The code works fine apart from there is another button with exactly the same markup, etc but the link shows SendEmailUsingOutlook (please see html below).

So i need to find the exact match of SendEmail and exclude SendEmailUsingOutlook.

P.S. I can't modify any of the HTML, CSS, etc this is generated by the system.

i am currently using:

window.attachEvent("onload",hideElement); 
 
function hideElement() 
{ 
for(i=0;i<document.all.length;i++) 
{
if(document.all[i].tagName=='A') 
{
if(document.all[i].href.search(/SubmitEmail/i)>-1) 
{
document.all[i].style.visibility = hidden;
}
}
}
}
 

The html buttons as generated from the CRM system:

<A CLASS=ButtonItem HREF="javascript:try{if(SubmitEmail            (true)==true) self.document.EntryForm.submit();}catch(err){alert('The path to local file is incorrect, please use Browse button to select file.')}"><IMG SRC="/CRM/Themes/img/color/Buttons/SendEmail.gif" BORDER=0 ALIGN=MIDDLE></A>
<A CLASS=ButtonItem HREF="javascript:try{if(SubmitEmailUsingOutlook(true)==true) self.document.EntryForm.submit();}catch(err){alert('The path to local file is incorrect, please use Browse button to select file.')}"><IMG SRC="/CRM/Themes/img/color/Buttons/SendOutlookEmail.gif" BORDER=0 ALIGN=MIDDLE></A></TD>

use .indexOf() to search for some characters in a String.

Ex:

  var str = "This is a Search String";
  var ind = str.indexOf("Search");

the ind will be -1 if the search string is no there. If it is there it will return starting index of the character sequence.

That wouldn't work as it'd still find the longer string. For a very simple solution, you could look for "SendEmail " (with a space).
