【liferay】1、使用alloy-UI发送ajax请求

1、首先liferay要发送ajax请求，那么就需要在jsp中定义resourceURL

<portlet:resourceURL var="workDeal" id="workDeal" />

2、然后我们如何使用alloy-ui读取数据？

这里我们可以借助alloy-ui提供的一个IO功能，发送ajax请求并从结果中读取数据

demo：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <link rel="stylesheet" href="../../build/aui-css/css/bootstrap.css">
    <script src="../../build/aui/aui.js"></script>
</head>
<body>
    <h1>AlloyUI - I/O demo</h1>
    <script>
    YUI({ filter:'raw' }).use('aui-io', function(Y) {

        Y.io.request('data/content.html', {
            on: {
                success: function() {
                    var data = this.get('responseData');
                    alert(data);
                }
            }
        });

    });
    </script>
</body>
</html>

这个案例中，是从一个文件中读取内容，然后alert输出

3、那么如果通过ajax请求获取数据，而不是读取文件呢？

function callWorkDeal(workDealUrl){
    
    var data = '';
    
    YUI({filter:'raw'}).use('aui-tabview', function(Y){
        Y.io.request(workDealUrl, {
            method:'get',
            on:{
                success:function(){
                    //处理数据
                    var recevieData = this.get('responseData');
                }
            }
        });
    });
}

可以通过这个函数来触发这个ajax操作，从而从后天获取对应的数据

4、如何展示tab页？

new Y.TabView({
            children: [
                {
                    label: 'foo',
                    content: '<p>foo content</p>'
                },
                {
                    label: 'bar',
                    content: '<p>bar content</p>'
                },
                {
                    label: 'fooz',
                    content: '<p>fooz content</p>'
                }
           ],
           srcNode: '#pills',
           type: 'pills'
        }).render();

效果类似：

5、通过ajax请求获取数据，展示在tab页中，这里使用的是liferay

<portlet:resourceURL var="workDeal" id="workDeal" />

<br/>
<div id="workDeal">
    <ul class="nav nav-tabs">
        <li class="active"><a href="#myWorkDeal">我的待办</a></li>
        <li><a href="#region">市待办</a></li>
        <li><a href="#province">省待办</a></li>
    </ul>
    <div class="tab-content">
        <div id=myWorkDeal>
        </div>
        <div id="region" class="tab-pane">
        </div>
        <div id="province" class="tab-pane">
        </div>
    </div>
</div>
<br/>

js部分

<script>
	YUI({filter:'raw'}).use('aui-tabview', function(Y){
		new Y.TabView({
		    srcNode: '#workDeal'
		}).render();
	});
	
	function <portlet:namespace/>showDaiban() {

		$.ajax({
			type:'POST',
			url:'<%=workDeal%>',
			data:'',
			dataType:'json',
			timeout:5000,
			cache:false,
			async:false,
			success:function(dealdata){
				//$('#ssoUrl').attr('href', dataurl);
				//data = dealdata;
				$.each(dealdata, function(n, value){

					//加上链接
	                var dealurl = eval("(" + value.content + ")");
					var content="";
	                $.each(dealurl, function(n, value){
	                	content += "<a href="" + value.url + "">" + value.text + "</a><br/>";
					});
	                
	                //拼接上
	                $('#' + value.label).html(content);
				});
				//去除最后一个，号
				if(lenjson > 0)
					tbody=tbody.substring(0,tbody.length-1);
				tbody += "]";
			},
			error:function(request){
				alert("connection error " + request);
			}
		});
	}
	
</script>
