Dojo DataGrid过滤器使用AndOrReadStore-我做错了什么?‏.



我有以下代码用于分别具有两列Column_AColumn_B的DataGrid:

grid.filter({Column_A: '*test*', Column_B: '*'}, true)

这段代码运行良好,可以查找Column_A中包含单词test的所有行……现在,我想做同样的操作,但查看任意一列。。。。逗号翻译成AND运算,但我正在寻找OR运算。

我阅读了AndOrReadStore的规范,根据我的理解,我应该能够做这样的事情:

grid.filter({complexQuery: "Column_A: '*test*' OR Column_B: '*'"}, true)

然而,这不起作用,我没有得到任何结果。。。我甚至不能让它与一个专栏一起工作,比如这个

grid.filter({complexQuery: "Column_A: '*test*'"}, true)

我做错了什么?

感谢

下面是一个工作程序示例(单击按钮调用筛选器: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%;
} 

我看了你发布的链接,我认为这是一个正确使用括号的问题。此外,看起来"复杂查询"用于对象,而"查询"用于字符串:

grid.filter({query: ("Column_A: '*test*' OR Column_B: '*'")}, true);
