Show and Hide Fields in Microsoft CRM

Show and Hide fields in Microsoft CRM: 

In this post I might want to present show and Hide fields in a Microsoft CRM structure dependent on through JavaScript. 

Here I will give tad clearness in my Microsoft CRM Fields . I have "lvt_opportunity" field and one more "tab_2" field. 

In "lvt_opportunity " field contains any information then naturally It will show "tab_2" Field or if "lvt_opportunity"doesn't contain information it will show away "tab_2" Field .

Show and Hide Feilds using javascript

function showHideTab() {
    debugger;
    var type = Xrm.Page.getAttribute("lvt_opportunity").getValue();

if (type == null) {

    Xrm.Page.ui.tabs.get("tab_2").setVisible(false);
    

}

else 

{

    Xrm.Page.ui.tabs.get("tab_2").setVisible(true);
   
}

}
