JavaScript tips for finishing _javascript skills

This article summarizes the small techniques of JavaScript. Share to everyone for your reference, specific as follows:

1. Organize default events

To block the default event, h5 the default input type= ' date ' has no effect on some browsers and Android devices, when you want to invoke the h5+ time selector, but to organize the default click event for input, the code is as follows:

Select Time
$ ("#end_time"). On ("click", Function (event) {
  event.preventdefault ();
  Plus.nativeUI.pickDate (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 ("Date not selected:" +e.message);
  },{ Title: "Please select Expiration Time", Mindate:new Date ()}); 

2. Determine if the input type= ' checkbox ' is selected, 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 one selected in multiple checkbox, the code is as follows

<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. Set CheckBox selection

Copy Code code as follows:

$ ("[name= ' checkbox ']:even"). attr ("Checked", ' true '); If this stuff doesn't work, please use Prop.

5. Get the value of the title property in more than one picture

User.id_pic1 = $ ($ ("#shopregister. Id_pic") [0]). attr ("title");
User.id_pic2 = $ ($ ("#shopregister. Id_pic") [1]). attr ("title");
USER.ID_PIC3 = $ ($ ("#shopregister. Id_pic") [2]). attr ("title");

6.ajax Show progress picture during submission

$.ajax ({
  type: ' POST ',
  url:configManager.RequstUrl + "/api/user/createstore",
  Data:postdata,
  Beforesend:function () {$ ("#waitingupload"). Removeclass ("Heisebghid"). AddClass ("HEISEBG");
Done (function (data) {
  $ ("#waitingupload"). Removeclass ("HEISEBG"). AddClass ("Heisebghid");
  if ("success" = = Data.state) {//server
   side successful
  }
  else
   {//Server side Failure
  }
}). Fail (function () {
  // Ajax request failed
});
