: Checked : matches all selected selected elements (check box, radio box, etc., excluding option in select)

Js:

JS Gets the checkbox value  
      var obj = document.getelementsbyname ("interest");//Selects all name= "Interest" objects, returns the array  
      var s= '; If you define VAR s in this way, the default is to assign a null value
      for (Var i=0;i<obj.length;i++) {
         if (obj[i].checked)//to an array of objects, We're going to loop around to check if it's not selected
         s+=obj[i].value+ ', ';  If selected, adds value to the variable s.  
      

Jquery:

jquery Get checkbox value  
      var chk_value =[];//defines an array  
      $ (' input[name= ' interest ']:checked '). each (function () {// Iterate through each check box named interest, where the selected execution function  
      Chk_value.push ($ (this). Val ());//Add the selected value to the array Chk_value  
      });
