重点打开jQuery UI ComboBox [英] Open jQuery UI ComboBox on focus

问题描述

我有一个jQuery ComboBox输入，当我专注时，我想自动打开自动完成菜单.

I have a jQuery ComboBox input that when focused I want to automatically open up the autocomplete menu.

但是，只需清除输入并像这样集中输入即可:

However, simply clearing the input and focusing it like this:

$('#select-id').val('').focus();

...不起作用.如果您手动聚焦自动完成器输入然后将其清除，则它会显示自动完成菜单.

...doesn't work. If you manually focus an autocompleter input and then clear it, it does display the autocomplete menu.

有没有一种方法可以触发自动完成菜单以打开焦点?我也希望它显示完整的菜单，因此我也想清除输入文本.

Is there a way I can trigger the auto complete menu to open on focus? I also would want it to show the complete menu, so I'd want to clear the input text as well.

推荐答案

假定您使用的是自动完成小部件的扩展组合框:

Assuming you're using the combobox that's an extension of the autocomplete widget:

$("your_selector").bind("focus", function () {
    this.value = '';
    $(this).autocomplete("search", '');
});

应该工作正常.
