您可以单击[-]按钮删除第一行(也是唯一的)过滤器行.它不应该被允许.绝对不允许删除第一过滤器行.
You can click on [-] button to remove the very first (and only) filter row. It shouldn't be allowed. First filter row should never be allowed to be removed.

推荐答案
I suggest to overwrite the internal reDraw method used by filtering (see my another answer for more description). To do this you should include in the searchOptions which you use the beforeShowSearch event handler with the following implementation:
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();
}
您可以在此处看到相应的演示.
