Use jquery to get a value for the selected state of a group or a single checkbox

Use jquery to get a value for the selected state of a group or a single checkbox.   This is illustrated by an example, assuming that there is an ID for the name of a set of checkboxes on an existing page, then the method to get the value of this set of Name=id checkboxes is as follows: JS code var id_array=new array ();   $ (' input[name= ' id "]:checked '). each (function () {Id_array.push ($ (). Val ());//add element to array}); var idstr=id_array.join (', ');//concatenate array elements to construct a string alert (IDSTR);

In addition jquery determines whether a single checkbox is selected and gets the selected values as follows: JS code if ($ ("#id"). Is (": Checked")) {//Select alert ($ ("#id"). Val ());//print selected value}
