篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Extjs4.0中 在 grid.Panel里添加复选框，但是如何可以取消那个可以全选的总的那个复选框相关的知识，希望对你有一定的参考价值。
参考技术A先根据类名把一组元素找出来，然后第一个元素就是那个你要去掉的复选框，对第一个元素设置样式就行了，代码如下。思路是这样的，我用的是Extjs6
//把头部的复选框去掉
var check = grid.getEl().select('div.x-column-header-text-wrapper');
check.elements[0].style.display = "none";
extjs ext5 Ext.grid.Panel 分页,搜索
带有分页,搜索的grid.
