/* added by Rajan Maharjan
* @param (array) arrayVar, (string) elementVar
* return (array) arrayVar;
* example : _splice(Array(1,2,3,4,5),4); will return Array(1,2,3,5);
*/
function _splice(arrayVar,elementVar){
//var returnRemovedArray=Array();
for(var p=0;p<arrayVar.length;p++){
if(arrayVar[p]==elementVar){
arrayVar.splice(p,1);
}
}
return arrayVar;
}

/* example goes here */
var newArray=splice(Array(1,2,3,4,5),4);
alert(newArray.join(“,”)); // alerts value 1,2,3,5
