我试图找出为什么过滤器功能不起作用,但我被卡住了。这是我第一次使用 Dojo,但我对那个框架并不熟悉。我正在尝试搜索 2 或 3 个小时,但我找不到解决方案。我想要的是实现过滤器或搜索机制。但它不起作用,但是......这是我的代码:
dojo.require('dojo.store.JsonRest');
dojo.require('dijit.layout.ContentPane');
dojo.require("dijit.form.Button");
dojo.require('dojox.grid.DataGrid');
dojo.require('dojo.data.ObjectStore');
dojo.require('dijit.form.TextBox');
dojo.require('dojox.data.AndOrReadStore');
dojo.require('dojo._base.xhr');
dojo.require('dojo.json')
dojo.require('dojo.domReady');
dojo.ready(
function(){
var appLayout = new dijit.layout.ContentPane({
id: "appLayout"
}, "appLayout");
var textBox = new dijit.form.TextBox({
name: "searchbox",
placeHolder: "Search ..."
});
var filterButton = new dijit.form.Button({
label: 'Filter',
onClick: function () {
searchWord = textBox.get('value');
query = "id: '"+searchWord
+"' OR date_A: '"+searchWord
+"' OR dateB: '"+searchWord
+"' OR product: '"+searchword+"'";
grid.filter({complexQuery: query}, true);
}
});
store = new dojo.store.JsonRest({target:'products/'});
grid = new dojox.grid.DataGrid(
{
store:dojo.data.ObjectStore({objectStore: store}),
structure:
[
{name:'id', field: 'id'},
{name:'date_A', field: 'dateA'},
{name:'date_B', field: 'dateB'},
{name:'product' , field: 'product'},
],
queryOptions: {ignoreCase: true}
});
textBox.placeAt(appLayout.domNode);
filterButton.placeAt(appLayout.domNode);
grid.placeAt(appLayout.domNode);
appLayout.startup();
}
);
如果你能告诉我这个 dojo 代码有什么问题,那就太好了……结果是,加载图标出现,过了一会儿,未过滤的数据显示出来……没有抛出异常。提前致谢。
