js怎么跟php结合使用

JavaScript和PHP可以相互嵌套，前提是JavaScript写在以.php为后缀的文件里面。

（1） JavaScript嵌套PHP：

直接在JavaScript里面写入PHP语句，如：

<script type="text/javascript">     BUI.use('bui/grid',function (Grid) {     var data = [//表单内容信息             <?php 		foreach($slice_rows as $key=>$val){ 		echo "{id:'".$val['id']."',imgpath:'".$val['imgpath']."',introduction:'".$val['introduction'].                "',linkpath:'".$val['linkpath']."',date:'".$val['date']."'},"; 	    } 	 	       echo "{id:'1112',imgpath:'李四',introduction:'this is a test',linkpath:'#',date:'date2'}"; 	   ?> 	],           grid = new Grid.SimpleGrid({           render : '#grid', //显示Grid到此处           width : 950,      //设置宽度           columns : [//表单头部信息             {title:'编号',dataIndex:'id',width:80},             {title:'图片路径',dataIndex:'imgpath',width:100}, 			{title:'简介',dataIndex:'introduction',width:200}, 			{title:'链接地址',dataIndex:'linkpath',width:100},             {title:'上传日期',dataIndex:'date',width:100}           ]         });       grid.render();       grid.showData(data);   });    </script>

（2）PHP嵌套JavaScript：

<?php 		 	echo '<script type="text/javascript">'; 	echo " BUI.use('bui/grid',function (Grid) {"; 	//表单的数据内容 	echo 'var data = ['; 	foreach($slice_rows as $key=>$val){ 		echo "{id:'".$val['id']."',imgpath:'".$val['imgpath']."',introduction:'".$val['introduction'].                      "',linkpath:'".$val['linkpath']."',date:'".$val['date']."'},"; 	} 	 	echo "{id:'1112',imgpath:'李四',introduction:'1349622209547',linkpath:'#',date:'date2'}"; 	 	echo '],'; 	//表单的头部信息 	echo " 	 grid = new Grid.SimpleGrid({           render : '#grid', //显示Grid到此处           width : 950,      //设置宽度           columns : [             {title:'编号',dataIndex:'id',width:80},             {title:'图片路径',dataIndex:'imgpath',width:100}, 			{title:'简介',dataIndex:'introduction',width:200}, 			{title:'链接地址',dataIndex:'linkpath',width:100},             {title:'上传日期',dataIndex:'date',width:100}           ]         }); 	 	"; 	echo '  grid.render(); 			grid.showData(data); 			});   '; 	 	 	//echo 'alert("this is a test")'; 	echo '</script>'; 	 ?>
