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>';
	
?>
