Substring or get a selected value in cellsrenderer:function

[Akshar AKParticipant]

Am checking a condition in the cellsrenderer function where i need to substring the value. Can you please suggest me how to do it? Here is the code of what am trying to do.

cellsrenderer:
function (row, column,value,data ) {
//Start:This snippet is added to rectify the milestone empty date issue. If a date is selected, there was no way to unselect a date or make the date empty
//if(value==’Thu Jan 1 05:30:00 UTC+0530 1970′){
alert(value.charCodeAt(0));
if
(value==‘Thu Jan 1 05:30:00 UTC+0530 1970’ || value==‘Wed Dec 31 16:00:00 PST 1969’ ){
return
‘<div> </div>’;
}
}
}

In the above code am checking a condition for VALUE. but i just need to check whether the string contains 1970 instead of the entire ‘Thu Jan 1 05:30:00 UTC+0530 1970’. Please let me know how to do that.

Hi Akshar,

For checking whether a string is contained within a string, you may use “indexOF” – http://www.w3schools.com/jsref/jsref_indexof.asp

Hello Peter,
If i use any of the JQuery or javascript functions like indexOf, jQuery :contains() Selector or substr it gives a javascript error. And the error is

SCRIPT438: Object doesn't support property or method 'indexOf' 
jqxgrid.js, line 7 character 103889

Hi Akshar,

Not sure how you use indexOf as it is a JavaScript function of the String. In addition, “cellsrenderer” should return HTML.

cellsrenderer:function (row, column,value,data ) {
var date = value.indexOf("1970");
alert(date);
if(date != -1){
return '<div> </div>';
}
}
			
		},

This is how i have used. Am i doing something wrong???

Hi Akshar,

It is possible the value to be a Date or Number object. As I already written, indexOf is method of the String object so you need to first convert the value to String and then use indexOf.

Akshar,
Following Peters’ instructions please try this

cellsrenderer:function (row, column,value,data ) {
    var date = value.toString().indexOf("1970");
    alert (date);
    if(date !== -1){
        return '<div> </div>';
    }
}

or this (which is a little cleaner)

cellsrenderer:function (row, column,value,data ) {
  if(value.toString().indexOf("1970")!== -1){
    return '<div> </div>';
  }
}
