extjs4动态生成多表头
通过json生成表头
效果图：
1 Ext.onReady(function () { 2 //header也就是你应该从后台取回的表头数据,现在写死在了这里 3 //var grid; 4 Ext.Ajax.request({ 5 params: { 6 parafdno: '', 7 parafcy: '', 8 pararepnum: '' 9 }, //发送的参数 10 url: "../BLL/H_yus/H_pinpdpfyysBLL.ashx?action=tlist", //请求的地址 11 success: function (response, option) { 12 //alert("rsptest:" + response.responseText); 13 var forminfo = Ext.decode(response.responseText); 14 //var forminfo = [{ name: 'company', header: 'Company' }, { name: 'price', header: 'Price' }, { name: 'change', header: 'change'}] 15 Ext.define('model', { 16 extend: 'Ext.data.Model', 17 fields: forminfo.fields, 18 validations: [{//满足该条件才会提交 19 type: 'length', 20 field: 'bennfpxse', 21 min: 1 22 }] 23 }); 24 var store = Ext.create('Ext.data.Store', { 25 //autoDestroy: true, 26 autoLoad: false, 27 autoSync: true, 28 model: 'model', 29 proxy: { 30 type: 'ajax', 31 //url: 'H_cuxfaBLL.ashx?action=list', 32 api: { 33 read: '../BLL/H_yus/H_pinprwfjBLL.ashx?action=read', 34 create: '../BLL/H_yus/H_pinprwfjBLL.ashx?action=create', 35 update: '../BLL/H_yus/H_pinprwfjBLL.ashx?action=update', 36 destroy: '../BLL/H_yus/H_pinprwfjBLL.ashx?action=destory' 37 }, 38 extraParams: { 39 'parafcy': '', 40 'parafdno': '', 41 'pararepnum': '' 42 }, 43 reader: { 44 type: 'json', 45 successProperty: 'success', //判断是否成功时的返回标题 46 root: 'items', //根目录 47 messageProperty: 'Msg'//返回的错误信息等其他信息的标题 48 }, 49 writer: { 50 type: 'json', 51 //writeAllFields: false, 52 encode: true, 53 root: 'items', //将提交行的数据易json格式传递到后台 54 allowSingle: false 55 }, 56 listeners: { 57 exception: function (proxy, response, operation) { 58 Ext.MessageBox.show({ 59 title: 'REMOTE EXCEPTION', 60 msg: operation.getError(), 61 icon: Ext.MessageBox.ERROR, 62 buttons: Ext.Msg.OK 63 }); 64 } 65 } 66 } 67 }); 68 //alert(forminfo.columns); 69 var columns = []; 70 var coms = []; 71 Ext.each(forminfo.columns, function (s) { 72 //alert(s); 73 coms.push({ 74 header: s.header, 75 dataIndex: s.name 76 }); 77 }); 78 Ext.define('grid', { 79 extend: 'Ext.grid.Panel', 80 store: store, 81 alias: 'widget.writergrid', 82 height: 300, 83 requires: ['Ext.grid.plugin.CellEditing', 'Ext.form.field.Text', 'Ext.toolbar.TextItem'], 84 85 initComponent: function () { 86 87 this.editing = Ext.create('Ext.grid.plugin.CellEditing'); 88 89 Ext.apply(this, { 90 iconCls: 'icon-grid', 91 frame: true, 92 defaultType: 'textfield', 93 viewConfig: { loadMask: new Ext.LoadMask(this, { msg: '正在加载数据...' }) }, 94 plugins: [this.editing], 95 dockedItems: [{ 96 xtype: 'toolbar', 97 items: [{ 98 iconCls: 'icon-add', 99 icon: '../Scripts/img/add.gif', 100 text: '加行', 101 disabled: false, 102 scope: this, 103 handler: this.onAddClick 104 }, { 105 iconCls: 'icon-delete', 106 icon: '../Scripts/img/delete.gif', 107 text: '减行', 108 disabled: true, 109 itemId: 'delete', 110 scope: this, 111 handler: this.onDeleteClick 112 }] 113 }], 114 columns: forminfo.columns 115 }); 116 this.callParent(); 117 this.getSelectionModel().on('selectionchange', this.onSelectChange, this); 118 }, 119 120 onSelectChange: function (selModel, selections) { 121 this.down('#delete').setDisabled(selections.length === 0); 122 selections = this.getView().getSelectionModel().getSelection()[0]; 123 }, 124 125 onSync: function () { 126 this.store.sync(); 127 }, 128 129 onDeleteClick: function () { 130 var selection = this.getView().getSelectionModel().getSelection()[0]; 131 if (selection) { 132 this.store.remove(selection); 133 } 134 }, 135 136 onAddClick: function () { 137 var rec = new model({ 138 shangpbm: '', 139 shangpmc: '', 140 guig: '', 141 fenl: 0, 142 fenlnew: 0 143 }), 144 edit = this.editing; 145 //this.store.reload(); 146 edit.cancelEdit(); 147 this.store.insert(0, rec); 148 edit.startEditByPosition({ 149 row: 0, 150 column: 0 151 }); 152 //alert(rec); 153 } 154 155 }); 156 157 initform(); 158 //grid.render('form-ct'); 159 } 160 }); 161 162 });

附加个json.net的写法
JObject jo = new JObject{ new JProperty("columns",new JArray( new JObject{ new JProperty("dataIndex","shangpbm"), new JProperty("header","商品编码"), new JProperty("field",new JObject{ new JProperty("xtype","textfield") }) }, new JObject{ new JProperty("dataIndex","shangpmc"), new JProperty("header","商品名称"), //new JProperty("width","320"), new JProperty("align","center"), new JProperty("field",new JObject{ new JProperty("xtype","textfield") }) }, from p in dth.AsEnumerable() select new JObject{ new JProperty("text",p["A1"].ToString()+p["A2"].ToString()), new JProperty("columns",new JArray( from q in dt.AsEnumerable() where q["A1"].ToString()==p["A1"].ToString() select new JObject{ new JProperty("dataIndex",q["ZACCTYP_0"]), new JProperty("header",q["ZACCDES_0"]), new JProperty("field",new JObject{ new JProperty("xtype","numberfield"), new JProperty("minValue","0") }) } ) ) } )), new JProperty("fields",new JArray( new JObject{ new JProperty("name","shangpbm") }, new JObject{ new JProperty("name","shangpmc") }, from q in dt.AsEnumerable() select new JObject{ new JProperty("name",q["ZACCTYP_0"]) } )) };
还有一个看到的似乎也异曲同工

还一个本来打算弄不出来的时候试试，后来没用着

1.创建DynamicGrid.js
Ext.define('Ext.grid.DynamicGrid',{
extend : 'Ext.grid.Panel',
alias : 'widget.dynamicgrid',
initComponent : function() {
var me = this;
var store = Ext.create('Ext.data.JsonStore', {
fields: [],
pageSize: 5,
proxy: {
type: 'ajax',
url : 'data.js',
reader: {
type: 'json',
root: 'recordList',
totalProperty : 'recordCount'
}
}
});
var headerCtCfg = {
items: [],
border: me.border
};
me.columns = headerCtCfg.items;
me.headerCt = Ext.create('Ext.grid.header.Container', headerCtCfg);
this.bindStore(store);
this.bbar.bindStore(this.store, true);
this.callParent();
},
onRender: function(ct, position) {
this.store.on('load', function(store, records) {
var jsonData = store.proxy.reader.jsonData;
if (typeof(jsonData.columns) === 'object') {
var columns = [];
if (this.rowNumberer) {
columns.push(new Ext.grid.RowNumberer());
}
if (this.checkboxSelModel) {
this.selModel = new Ext.selection.CheckboxModel();
}
Ext.each(jsonData.columns, function(column) {
columns.push(column);
});
var store = Ext.create('Ext.data.Store', {
fields : jsonData.fields,
data : jsonData.recordList
});
this.reconfigure(store, columns);
this.render();
}
}, this);
this.store.load();
Ext.grid.DynamicGrid.superclass.onRender.call(this, ct, position);
}
});
2.创建grid
var dynamicGrid = Ext.create('Ext.grid.DynamicGrid', { title: '测试动态列', renderTo: 'dynamic-grid', storeUrl: 'data.json', width : 600, height: 300, store: store, rowNumberer: true, checkboxSelModel: false, bodyStyle: 'padding-top: 22px', //不知道什么原因，列头会把第一行给覆盖，所以需要加上这个样式 bbar : new Ext.PagingToolbar({ store: store, pageSize: 5, displayInfo: true, displayMsg: '显示第{0}到{1}条数据,共{2}条', emptyMsg: "没有数据", beforePageText: "第", afterPageText: '页 共{0}页' }) });
返回的数据格式：
{ 'fields': [ {'name': 'id', 'type': 'int'}, {'name': 'name', 'type': 'string'}, {'name': 'sex', 'type': 'boolean'} ], 'success': true, 'recordCount': 50, 'recordList': [ {'id': '1', 'name': 'AAA', sex: 1}, {'id': '2', 'name': 'BBB', sex: 1}, {'id': '3', 'name': 'CCC', sex: 0}, {'id': '4', 'name': 'DDD', sex: 1}, {'id': '5', 'name': 'EEE', sex: 1} ], 'columns': [ {'header': 'ID', 'dataIndex': 'id'}, {'header': 'User', 'dataIndex': 'name'}, {'header': 'SEX', 'dataIndex': 'sex'} ] }
