JQuery multiselect selectedText does not work with JQuery > 1.4.2 when select list contains only one element

This is the problem with the change in the jquery version. Previous jquery(up to 1.4.2) the checkbox checked can be found by using "[checked]". Later versions of jquery changed to ":checked". To fix this issue go the jquery multiselect plugin js file line number 206 and change  $checked = $inputs.filter('[checked]') to $checked = $inputs.filter(':checked'). This solution works for me.

JavaScript fuction for ReplaceAll

The solution to replace all using javascript is as follows:
String.prototype.ReplaceAll = function(stringToFind,stringToReplace){

var temp = this;

var index = temp.indexOf(stringToFind);

while(index != -1){

temp = temp.replace(stringToFind,stringToReplace);

index = temp.indexOf(stringToFind);

}

return temp;

}

Javascript function for InitCaps

The following is the simple code for converting the given string in to the init caps using javascript
function initcaps( string ) {
/* The following  Regex Replace  will  Identify  First Character
from the Word and  makes  it to  Uppercase and remaining
text to lower case */
/* This function consider only Alphanumeric Not  any 
Special Characters.*/

string =string.replace( /(\b\w)([a-zA-Z0-9]+)/gi,
function(t,a,b) { return a.toUpperCase() + b.toLowerCase(); } );
return string;
}
