jQuery plug in Easyui setting pageNumber of datagrid causes a solution to the problem of two requests

This article illustrates how the jQuery plug-in Easyui sets pageNumber of datagrid to solve the problem of two requests. Share it for your reference, as follows:

1. Problem description:

$('#tb-page-list').datagrid({
    url: '/BisOrderInfo/GetList',
    pageNumber: 2,
    pageSize: 10
});

When the pageNumber is manually set to be greater than or equal to 2, when viewing the requested method, the request will be made twice, and the pageNumber of the second time is equal to 1;

2. Why:

Line 7821-7828 in jquery. easyui. min. js 1.3. 4;

Because the paging control initialization parameters total = = 0 and pageNumber = = 1, the parameters of the first request for page 2 are different from the control initialization parameters, resulting in a second request: _ 5dc (_ 545);

Solution: When the page is refreshed, the total amount of data requested changes and the display of pagebar needs to be updated.

3. Solutions:

Line 7822 (note version 1.3. 4 jquery. easyui. min. js):

_54a.pagination("refresh",{total:data.total});

Amend to read:

_54a.pagination("refresh",{pageNumber:opts.pageNumber||_54b.pageNumber,total:data.total});
