我正在 JqGrid 上尝试非常简单的搜索弹出窗口。请参阅下面的代码。有几个问题：
The popup comes up with AND/OR and [+] controls at the very top. See screenshot below: (from FF 4)
您可以单击 [-] 按钮删除第一个（也是唯一一个）过滤器行。不应该允许。绝不允许删除第一个过滤器行。

我建议覆盖内置的reDraw过滤使用的方法（参见我的另一个答案以获得更多描述）。为此，您应该将其包含在searchOptions你使用的beforeShowSearch事件处理程序具有以下实现：
beforeShowSearch: function($form) {
var searchDialog = $form[0],
oldrReDraw = searchDialog.reDraw, // save the original reDraw method
doWhatWeNeed = function() {
$('input.delete-rule:first',searchDialog).unbind('click');
// set fucus in the last input field
setTimeout(function() {
// set fucus in the last input field
$('input[type="text"]:last',searchDialog).focus();
}, 50);
}
searchDialog.reDraw = function() {
oldrReDraw.call(searchDialog); // call the original reDraw method
doWhatWeNeed();
}
doWhatWeNeed();
}
