一般的情况下我们使用jGrid表格在浏览器下出现undefine的错误。很是嫌人，现在总结为以下的两个解决方案。
1、如果你的版本比较老不是4.0的版本的话，一般情况下安装webkit上的说明来安装你的js文件就可以了，也就是说你需要包括<script src="js/i18n/grid.locale-en.js" type="text/jscript"></script>这个js文件而且你的顺序需要固定按照：
<script src="js/jquery-1.5.2.min.js" type="text/javascript"></script>
<script src="js/i18n/grid.locale-en.js" type="text/jscript"></script>
<script src="js/jquery.jqGrid.min.js" type="text/javascript"></script>
这个顺序，在firefox下才不会出现undefine,在chrome下面是不会出现这个错误的
2、如果你的版本比较新的话，就需要按照我的一下这个顺来安装你的js文件，才不出现undefine
<script src="js/jquery-1.5.2.min.js" type="text/javascript"></script>
<script src="js/grid.loader.js" type="text/javascript"></script>
<script src="js/jquery.fmatter.js" type="text/javascript"></script>
<script src="js/i18n/grid.locale-en.js" type="text/jscript"></script>
<script src="js/jquery.jqGrid.min.js" type="text/javascript"></script>
<script src="js/jquery-ui-1.8.2.custom.min.js" type="text/javascript"></script>
测试的代码：
<table id="list47"></table> <div id="plist47"></div>
<script type="text/javascript">
