Jquery. validate1.9.0 front-end verification, jquery front-end Paging

I. Use the jquery. form plug-in to submit a form using the jquery. validate plug-in

Symptom: When a form is submitted, the form is submitted as usual even if the front-end fails to pass the verification.

Solution:

 

[Php]View plaincopy

1. $ ('# MyForm'). submit (function (){
2. If (! $ (This). valid () return false; // Add this sentence OK
3. ('.Error'{.html ('');
4. $ ("# Go"). prop ("disabled", true );
5. $ (This). ajaxSubmit ({
6. Type: "POST ",
7. // BeforeSubmit: showRequest,
8. DataType: 'json ',
9. Success: showResponse
10. });
11. Return false;
12. });

Instructions:

 

Custom submission method (ajax submission)
If ajax is used for submission, use the following two methods in combination with the verification framework:
1) Configure ajax submission using the submitHandler attribute. submithandler: When all the forms are verified, the configuration code will be called back. In this case, ajax is called for submission after the verification is passed.
2) use the valid method to listen to the form submit event and submit it again when $ ('# form'). valid () returns true.

You can use ajax to submit a form by listening to the form submit event. The complete sample code is as follows:

 

[Php]View plaincopy

1. $ (Document). ready (function (){
3. $ ('# MyForm'). submit (function (){
4. If (! $ (This). valid () return false;
5. ('.Error'{.html ('');
6. $ ("# Go"). prop ("disabled", true );
7. $ (This). ajaxSubmit ({
8. Type: "POST ",
9. // BeforeSubmit: showRequest,
10. DataType: 'json ',
11. Success: showResponse
12. });
13. Return false;
14. });
16. Var validator = $ ("# myForm"). validate ({
17. Rules :{
18. Username: "required ",
19. Email :{
20. Required: true,
21. Email: true
22. }
23. },
24. Messages :{
25. Username: "enter your name ",
26. Email :{
27. Required: "Enter the Email address ",
28. Email: "enter the correct email address"
29. }
30. }
31. });
33. });
35. Function showResponse (jsonData, statusText)
36. {
37. If (statusText = 'success ')
38. {
39. $ ("# Go"). prop ("disabled", false );
40. If (jsonData. status = 1)
41. {
42. $ ("# Return" response .html (jsonData. message );
43. }
44. Else
45. {
46. $. Each (jsonData. errors, function (k, v ){
47. // $ ('# Output'). find ('ul'). append ('<li>' + v + '</li> ');
48. $ ('. E _' + k).html (v );
49. });
50. }
51. }
52. }

Ii. Methods for controlling the location of error messages

Symptom 1:

I added a new verification code to the Registry ticket. When the verification result is incorrect, the error message goes to the front of the verification code. As shown in:

Purpose: To keep the error message behind the verification code

Symptom 2:

In red, I want to move to the end of (* required.

The above two phenomena can be used to control the location of error messages through the method 'errorplacement 'provided by jquery. validate, which is also convenient to use:

 

[Php]View plaincopy

1. ErrorPlacement: function (error, element)
2. {
3. Error. appendTo (element. parent ());
4. }

 

Jqueryvalidatejs verification. What should I do when I go to the database verification email address?

This jquery. validate. js can only be used for foreground verification, that is, to verify whether the input meets the requirements.

In jquery validate, remote verification is returned in the background correctly, but the foreground does not respond.

Press ctrl + shift + j in chrome to open the console and check for JS errors.
I can say exactly that your ajax failed.
