I got the answer to it in the initialization of autocomplete widget...just add
我在自动完成小部件的初始化中得到了答案......只需添加
$(this.target).find('input').autocomplete();
This will initialize the autocomplete widget this happened because in 1.10.*.Jquery has added error messages for usage of functions without proper initialization whereas it was not there in previous versions.
这将初始化发生这种情况的自动完成小部件，因为在1.10.*.Jquery 中添加了错误消息，用于在没有正确初始化的情况下使用函数，而在以前的版本中没有。

If you want to make sure the autocomplete widget is destroyed, you can check if it was actually initialized by inspecting the CSS classes of the target element, e.g.
如果你想确保自动完成小部件被销毁，你可以通过检查目标元素的 CSS 类来检查它是否真的被初始化，例如
if ($target.hasClass('ui-autocomplete')) {
$target.autocomplete('destroy')
}

I was getting similar error regarding the widget call,
关于小部件调用，我遇到了类似的错误，
Inside the autocomplete initialization, we were calling its widget function, that was creating the console error.
在自动完成初始化中，我们调用了它的小部件函数，该函数正在创建控制台错误。
In test-result.component.ts,
在 test-result.component.ts 中，
(<any> window).$(testelementId).autocomplete({
……..
(<any> window).$(this).autocomplete('widget').css('width', '100%');
…..
})
So, the easiest fix was to remove that particular call or place it after the initialization and test if that breaks any style. For me, removing the widget call is not doing any harm, so went ahead with that.
因此，最简单的解决方法是删除该特定调用或将其放置在初始化之后，并测试是否会破坏任何样式。对我来说，删除小部件调用不会造成任何伤害，所以继续这样做。
