免费的 jqgrid 工具栏禁用按钮在鼠标单击时生成单击事件。In 导致无效的代码执行。要重现，请在 Chrome 中打开页面 belwo，然后单击禁用的内联编辑或分页器按钮。矩形出现并保持在按钮周围。点击方法代码被执行。
我通过添加检查解决了这个问题
if (p.savedRow === undefined || p.savedRow.length === 0)
return;
到 jqgrid 源代码：
if (o.save) {
$self.jqGrid("navButtonAdd", elem, {
caption: o.savetext || "",
title: o.savetitle || "Save row",
commonIconClass: o.commonIconClass,
buttonicon: o.saveicon,
iconsOverText: o.iconsOverText,
id: gid + "_ilsave",
onClickButton: function () {
// PATCH if removed clicking in disabled save button causes exception
if (p.savedRow === undefined || p.savedRow.length === 0) {
return;
}
// END
但是 jqgrid 不应该触发 thois 方法。
如何解决这个问题？
