Collaps And Uncollaps Is Not Working In My Script

i have used Master Nested Grid View in my project, it can list all Lots based on its Packages, but Collapse/UnCollapses is not working in my script the error is .live is not a func

Solution 1:

.live is deprecated and removed in jquery version 1.9 and further. use .on instead:

$("#gridT").on("click",'.hoverEff',function(){
        $(this).toggleClass("expand collapse");
        $(this).parent().closest("tr").next().slideToggle(100);
});
