[英]How to profile JQuery/JQGrid

原文 2010-01-19 15:37:50 7 2 javascript/ jquery/ debugging/ jqgrid

I am using JQGrid component for displaying ajax tree grid. 我正在使用JQGrid组件显示ajax树形网格。 With some quantity of data (tree with 200 branches, 2-3 items in each) - the grid begins to freeze in FireFox. 有了一定数量的数据（带有200个分支的树，每个分支中有2-3个项目），网格开始在FireFox中冻结。 Then I get a window asking whether to stop the script or continue. 然后我得到一个窗口，询问是停止脚本还是继续。

What is the prescription to debug and resolve this? 调试和解决此问题的处方是什么？ I can debug my code, but I am not sure how to debug js libraries and their nuances. 我可以调试我的代码，但不确定如何调试js库及其细微差别。

Is it more likely JQuery, JQGrid or FireFox problem? 更有可能是JQuery，JQGrid或FireFox问题吗？

2 个解决方案

Use Firebug or IE 8's profiler to trace down the problem. 使用Firebug或IE 8的探查器来查找问题。

Note that jqGrid got significantly faster if you enable the gridview option in jqGrid 3.5+, though I don't think that works for trees. 请注意，如果您在jqGrid 3.5+中启用gridview选项，则jqGrid的速度将显着提高，尽管我认为这不适用于树木。 But start with the profiler. 但是从分析器开始。
