自动完成后触发 Onchange 事件 [英] Fire Onchange event after AutoComplete

问题描述

我正在尝试一次执行 Autocomplete 和 onchange 事件.

意思是:我想在自动完成文本框中触发 onchange 事件.当我从键盘在文本框中写一些东西并在文本框外单击然后 onchange 事件触发但是当我从自动建议名称中选择某些内容时 onchange 事件没有触发.

我的 HTML 代码

人名:<input id="txt0" type="text" onchange="SaveData('txt0')" class="userSearch" placeholder="Helped Person"/>

JavaScript 代码

function AutoComplete() {//自动完成添加到文本框.$('.userSearch').自动完成({来源:功能(请求，响应){$.ajax({url: "CTC.aspx/GetMemberName",数据:{'prefixText':'"+ request.term +'}"，数据类型:json"，类型:POST"，contentType: "application/json; charset=utf-8",成功:功能(数据){响应(数据.d)},错误:函数(XMLHttpRequest，textStatus，errorThrown){alert('自动完成时出错');}});},最小长度:1});}函数 SaveData(textBoxId) {警报(文本框Id)；}

我想在从自动完成中选择后触发 onchange 事件.

请帮忙

提前致谢.

解决方案

您可以使用自动完成小部件上的更改事件来实现此目的.http://api.jqueryui.com/autocomplete/#event-change

例如:

function AutoComplete() {//自动完成添加到文本框.$('.userSearch').自动完成({来源:功能(请求，响应){//你的ajax代码},最小长度:1，更改:函数(事件，用户界面){ SaveData();}});}

解决方案

You can use the change event on the autocomplete widget to achieve this. http://api.jqueryui.com/autocomplete/#event-change

For example:

function AutoComplete() {
  //Autocomplete added to the textbox.
  $('.userSearch').autocomplete({
      source: function (request, response) {
         // your ajax code
      },
      minLength: 1,
      change: function (event, ui) { SaveData(); }
  });
}
