1. Organize default events

Block default events, h5 default input type= ' date ' has no effect on some browsers and Android devices, call the h5+ time selector, but organize the input default click event with the following code:

 //  select time  $ ("#end_time"). On ("click"        , function   function   (E) {  var  D = e.date;  //             Console.log (D.format (' yyyy-mm-dd '));         $ ("#end_time"). Val (D.format (' Yyyy-mm-dd '  function   (E) {Console.log ( "not        Select Date: "+e.message); },{title:  Select expiry time, Mindate:new   Date ()        }); });

2. Determine if input type= ' checkbox ' is selected and the code is as follows

    if (!$ ("#shopregister #checkaggree"). Is (": Checked")) {        alert ("Please agree to the registration agreement");         return false ;    }

3. Get the value of the selected one in multiple checkboxes, as shown in the code below

<input name= ' is_refund ' id= ' refund_1 ' type= ' Radio ' value= ' 1 '/><input name= ' is_refund ' id= ' refund_0 ' checked= ' Checked ' type= ' radio ' value= ' 0 '/>$ ("#shopregister input[name= ' is_refund ']:checked '). Val ();

4. Get the value of the title property in multiple pictures

    User.id_pic1 = $ ($ ("#shopregister. Id_pic") [0]). attr ("title");     = $ ($ ("#shopregister. Id_pic") [1]). attr ("title");     = $ ($ ("#shopregister. Id_pic") [2]). attr ("title");
