先看代码
<!DOCTYPE html> <html lang="en"> <head> <meta charset="gb2312"/> <title>增加,删除行</title> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/default/easyui.css"/> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/icon.css"/> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/demo.css"/> <script type="text/javascript" src="../easyui-ku/jquery.min.js"></script> <script type="text/javascript" src="../easyui-ku/jquery.easyui.min.js"></script> <script type="text/javascript"> $(‘#dg‘).datagrid({ columns:[[ {field:‘itemid‘,title:‘Item ID‘,width:80,sortable:true}, {field:‘productid‘,title:‘Product ID‘,width:80,sortable:true}, {field:‘product‘,title:‘Item Details‘} ]] }); </script> </head> <body> <table id="dg" class="easyui-datagrid" style="width:400px;height:250px"> </table> </body> </html>
这代码写完后,打开浏览器运行。原以为能看到datagrid的列名,但实际上没有看到。找了一些资料,也没有发现解决的方法。后来问了一位高人,他说以前这样是可以的,现在不行了,原因是html加载是从上到下的,也就是说id="dg"这个标签还没加载,下面的代码是无法控制id=“dg”的显示样式的。
<script type="text/javascript"> $(‘#dg‘).datagrid({ columns:[[ {field:‘itemid‘,title:‘Item ID‘,width:80,sortable:true}, {field:‘productid‘,title:‘Product ID‘,width:80,sortable:true}, {field:‘product‘,title:‘Item Details‘} ]] }); </script>
听他说完我就把上面的代码换了一个位置发现果然行了,以下是改变位置后的代码:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="gb2312"/> <title>增加,删除行</title> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/default/easyui.css"/> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/icon.css"/> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/demo.css"/> <script type="text/javascript" src="../easyui-ku/jquery.min.js"></script> <script type="text/javascript" src="../easyui-ku/jquery.easyui.min.js"></script> </head> <body> <table id="dg" class="easyui-datagrid" style="width:400px;height:250px"> </table> <script type="text/javascript"> $(‘#dg‘).datagrid({ columns:[[ {field:‘itemid‘,title:‘Item ID‘,width:80,sortable:true}, {field:‘productid‘,title:‘Product ID‘,width:80,sortable:true}, {field:‘product‘,title:‘Item Details‘} ]] }); </script> </body> </html>
或者也可以这样:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="gb2312"/> <title>增加,删除行</title> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/default/easyui.css"/> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/icon.css"/> <link rel="stylesheet" type="text/css" href="../easyui-ku/themes/demo.css"/> <script type="text/javascript" src="../easyui-ku/jquery.min.js"></script> <script type="text/javascript" src="../easyui-ku/jquery.easyui.min.js"></script> <script type="text/javascript"> $(function(){ $(‘#dg‘).datagrid({ columns:[[ {field:‘itemid‘,title:‘Item ID‘,width:80,sortable:true}, {field:‘productid‘,title:‘Product ID‘,width:80,sortable:true}, {field:‘product‘,title:‘Item Details‘} ]] }); })(); </script> </head> <body> <table id="dg" class="easyui-datagrid" style="width:400px;height:250px"> </table> </body> </html>
