Sandeep Singh Shekhawat · Answer

Use following code to check a value in array: function getValue() { var typesArray = new Array( "SK" , "SK 2" , "SK 4" , "XYZ TYPE" ); var cType = 'XYZ TYPE' ; for ( var j = 0; j { if (typesArray[j].match(cType)) { alert( "It exists in array" ); } } }

Hi Shehzad, You can't use NOT IN operator in if condition because javascript doesn't support it. If you want use NOT IN then you can use like following code: function NotInOperator() { var typesArray = new Array( "SK" , "SK 2" , "SK 4" ); var cType = 4; if (!(cType in typesArray)) { alert( "It does not exist in array" ); } } Thanks Sandeep

Hi Sandeep, Index will not work for cType NOT IN Regards

Sandeep Singh Shekhawat · Answer

You must specify index number instead of value of that index because IN operator in javascript works for index number. for example: script type ="text/javascript"> function InOperator() { var typesArray = new Array( "SK" , "SK 2" , "SK 4" ); var cType=1; if (cType in typesArray) { alert( "It exists in array" ); } } script > Thanks Sandeep Shekhawat
