此进度条分页器EXTJS网格在EXTJS5中运行，但在EXTJS 4中无效。因此，如何使其在EXTJS 4中运行。 这是一个简单的extJS 4网格，具有分页支持。我希望我的EXTJS 4网格支持分页。如何使我的EXTJS 4网格分页？ 我目前的代码是

我现在遇到了同样的问题。你有2个解决方案。第一个是使用grid的grid.reconfigure（）方法重新配置网格或删除旧网格并使用新商店创建新网格，新的总属性，新数据和第二个有点难以解释，考虑到我的英语知识但我会尝试。首先，你不能手动解析json，你不应该使用add方法将其添加到store，而是必须始终通过其代理设置加载store。而重要的部分。每个新页面响应的总属性必须比页面大小多一个......好吧，它比我想象的更难解释。这是示例
存储代理配置：
Ext.define('ExtMVC.store.myStore', {
extend: 'Ext.data.Store',
storeId: 'MyStore',
pageSize : 100,
autoLoad:true,
proxy: {
type: 'ajax',
url: 'ajax/?getData',
reader: {
type: 'array',
root: 'data',
totalProperty: 'count'
}
},
fields: [{
name: 'company'
}, {
name: 'price'
}, {
name: 'change'
}, {
name: 'pctChange'
}, {
name: 'lastChange'
}]
});
服务器配置：示例在php
中<?php
session_name("test");
session_start();
$page = $_REQUEST["page"];
$start = $_REQUEST["start"];
$data = [];
for ($i=0; $i < $start+100; $i++) {
$data[]=["ipsa".$i, "ut".$i, "dignissimos".$i, "recusandae".$i, "quae".$i];
}
$_SESSION["start"] = $start+1;
echo json_encode(["count"=>$start+101,"data"=>$data]);
?>

我已将您的代码更改为使用分页。重要的变化：在创建商店之前生成数据，以便在代码中添加数据而不是通过方法＆＃34;添加＆＃34;。我已将读者添加到读者计数（分页插件使用的记录总数）。还adddockedItems pagingtoolbar实际使用分页工具栏，这里是代码，它必须工作
