我使用以下代码处理分别具有两列Column_A和Column_B的DataGrid:
grid.filter({Column_A: '*test*', Column_B: '*'}, true)
这段代码可以正常工作，并找到
Column_A中包含单词test的所有行...现在，我想做同样的事情，但是在任一列中查找....逗号转换为AND操作，但我正在寻找或运算。我阅读了AndOrReadStore specs，根据我的理解，我应该能够执行以下操作:
grid.filter({complexQuery: "Column_A: '*test*' OR Column_B: '*'"}, true)
但是，这是行不通的，而且我也没有得到任何结果。。。
grid.filter({complexQuery: "Column_A: '*test*'"}, true)
我究竟做错了什么？
谢谢
最佳答案
这是一个可行的编程示例(单击按钮以调用过滤器:Column_A包含e或Column_B为300):
JavaScript(script.js):
dojo.require("dijit.layout.ContentPane");
dojo.require("dijit.form.Button");
dojo.require("dojox.grid.DataGrid");
dojo.require('dojox.data.AndOrReadStore');
dojo.ready(function(){
var appLayout = new dijit.layout.ContentPane({
id: "appLayout"
}, "appLayout");
var data = {
'items': [
{'Column_A': 'alpha', 'Column_B': '100'},
{'Column_A': 'beta', 'Column_B': '200'},
{'Column_A': 'gamma', 'Column_B': '300'},
{'Column_A': 'delta', 'Column_B': '400'}
]
};
var store = new dojox.data.AndOrReadStore({
data: data
});
var layout = [[
{name : 'A', field : 'Column_A', width : '125px'},
{name : 'B', field : 'Column_B', width : '100%'}
]];
var grid = new dojox.grid.DataGrid({
structure : layout,
store: store,
queryOptions: {ignoreCase: true}
});
var filterButton = new dijit.form.Button({
label: "Filter",
onClick: function () {
grid.filter({complexQuery: "Column_A: '*e*' OR 'Column_B: '300'"});
}
});
filterButton.placeAt(appLayout.domNode);
grid.placeAt(appLayout.domNode);
appLayout.startup();
});
现在是html(index.html)
<html lang="en">
<head>
<meta charset="utf-8">
<title>DataGrid with AndOrReadStore</title>
<link rel="stylesheet" href="style.css" media="screen"/>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.7.1/dijit/themes/claro/claro.css" />
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.7.1/dijit/themes/claro/document.css" />
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.7.1/dojox/layout/resources/ExpandoPane.css" />
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.7.1/dojox/grid/resources/claroGrid.css">
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/dojo/1.7.1/dojox/grid/enhanced/resources/claro/EnhancedGrid.css">
<script src="http://ajax.googleapis.com/ajax/libs/dojo/1.7.1/dojo/dojo.js" type="text/javascript"></script>
<script src="script.js" type="text/javascript"></script>
</head>
<body class="claro">
<div id="appLayout"></div>
</body>
</html>
最后是CSS(style.css)
html, body {
width: 100%; height: 100%;
margin: 0; padding: 0;
overflow: hidden;
}
#appLayout {
width: 100%; height: 100%;
}
