Question

请教GRID表格列中加入了复选框，但不可修改值

Answer 1

extjs自己提供复选框列// checkbox列var filecheckbox = new Ext.grid.CheckboxSelectionModel();// GridPanelvar fileGrid = new Ext.grid.GridPanel({store : fileStore,columns : [new Ext.grid.RowNumberer(), //显示列数filecheckbox,//显示复选框列{//其他显示列}]//省略其他属性});这样你就可以而得到一个复选框，可以进行单选、全选了如果你想自己定义的话，也可以//定义filtersvar filters = new Ext.ux.grid.GridFilters({ // encode and local configuration options defined previously for easier reuse encode: encode, // json encode the filter query local: local, // defaults to false (remote filtering) filters: [{ type: 'numeric', dataIndex: 'id' }, { type: 'string', dataIndex: 'company', disabled: true }, { type: 'numeric', dataIndex: 'price' }, { type: 'date', dataIndex: 'date' }, { type: 'list', dataIndex: 'size', options: ['small', 'medium', 'large', 'extra large'], phpMode: true }, { type: 'boolean', dataIndex: 'visible' }] });// use a factory method to reduce code while demonstrating // that the GridFilter plugin may be configured with or without // the filter types (the filters may be specified on the column model var createColModel = function (finish, start) { var columns = [{ dataIndex: 'id', header: 'Id', // instead of specifying filter config just specify filterable=true // to use store's field's type property (if type property not // explicitly specified in store config it will be 'auto' which // GridFilters will assume to be 'StringFilter' filterable: true //,filter: {type: 'numeric'} }, { dataIndex: 'company', header: 'Company', id: 'company', filter: { type: 'string' // specify disabled to disable the filter menu //, disabled: true } }, { dataIndex: 'price', header: 'Price', filter: { //type: 'numeric' // specify type here or in store fields config } }, { dataIndex: 'size', header: 'Size', filter: { type: 'list', options: ['small', 'medium', 'large', 'extra large'] //,phpMode: true } }, { dataIndex: 'date', header: 'Date', renderer: Ext.util.Format.dateRenderer('m/d/Y'), filter: { //type: 'date' // specify type here or in store fields config } }, { dataIndex: 'visible', header: 'Visible', filter: { //type: 'boolean' // specify type here or in store fields config } }]; return new Ext.grid.ColumnModel({ columns: columns.slice(start || 0, finish), defaults: { sortable: true } }); };然后 var grid = new Ext.grid.GridPanel({ colModel: createColModel(4), plugins: [filters], //这两个属性是重点，加上去就可以了 });效果看图片。建议你去下载官方的源代码，然后看其中的例子。里面有一个就是如何自定义这个的
