I remember that I used similar Extjs3 functions before. The Code is as follows: store. on ("" beforeload "", function () {Ext. apply (this. baseParams, {name: _ name, phone_num: _ phone}) ;}); pagingtoolbar page, in store. load ({params: {type: type_combo.getValue ()}) with parameter query. By default, only one page can be queried. When paging to the next page, there is no parameter. The solution is to assign a value to the page parameter before the store is loaded. The method used in Ext3 is: store. on ("" beforeload "", function () {store. baseParams = {type: type_combo.getValue () };}); the above method is no longer effective in Ext4 and should be changed to store. on ("beforeload", function () {Ext. apply (store. proxy. extraParams, {type: type_combo.getValue ()});});
