jQuery自动完成：点击返回提交表单 [英] jQuery Autocomplete: Hitting return submits the form

问题描述

我正在使用jQuery Autocomplete插件。

I am using the jQuery Autocomplete plugin.

// I'm not sure if there's a better way to do this

var base_url = window.location.href.slice(0, window.location.href.indexOf('/bar'));
$('.foo-widget').find('input:first-child').autocomplete(base_url + "/api/baz?format=newline");

加价：

<ul class="foo-widget">
    <li>
        <input value="" autocomplete="off" class="ac_input"><input value="" autocomplete="off" class="ac_input"><button>Add</button>
   </li>
</ul>

这很好用。但是，当我点击输入从自动填充结果中选择一个项目时，表单会提交。为什么会发生这种情况？

This works fine. However, when I hit "enter" to choose an item from the autocomplete results, the form submits. Why might this be happening?

我查看了 jquery.autocomplete.js 并看到以下内容正在执行：

I looked into jquery.autocomplete.js and saw that the following is being executed:

        case KEY.RETURN:
            if( selectCurrent() ) {
                // stop default to prevent a form submit, Opera needs special handling
                event.preventDefault();
                blockSubmit = true;
                return false;
            }
            break;

不应该 event.preventDefault（）和 blockSubmit = true 停止提交表单？我在页面上其他地方的JS代码是否可能会干扰？

Shouldn't event.preventDefault() and blockSubmit = true stop the form from submitting? Is it possible that JS code I have elsewhere on the page is interfering?

推荐答案

我建议在自动完成时添加按键事件元素并从中返回false。它不会影响您以后提交表格其余部分的能力。

I would recommend adding an keypress event on the Autocomplete element and return false from that. It will not impact your ability to submit the rest of the form at a later time.
