我正在尝试使用我的列表中的单击事件来提取街道的名称,使用AJAX成功回调获取地址数据的整个过程完美地运行我添加了一个成功的客户对话框,其中包含他点击的街道信息.
但是在成功对话的街头表演时,我想获得街道名称并将其传输到隐藏的输入,我希望使用该街道的名称,以便将来客户点击按钮时复制表单的地址AJAX,可以使用此街道的名称在我的API中进行搜索,以便返回此操作返回该地址的扩展版本到我的表单.
但我无法思考或找到任何关于如何仅提取客户端在列表中单击的街道名称的任何内容,只有他可以返回给我的是使用来自我的API的路径在列表分组开始时生成的原始元素包含所有注册的地址
我已经尝试通过生成的元素的类获取数据,但没有结果..我曾想过尝试将ID添加到被点击的地址但我在jQuery文档中找不到任何可以帮助我的东西.
我的elements.js
$(document).ready(function(){
// Setup Modal
$('#openSearchAddress').click(function() {
// Start Modal
$('#modalSearchAddress')
.modal('show')
;
});
$('#sendSearchAddress').click(function() {
$.ajax({
type: "GET",
dataType: "JSON",
url: "https://****-api.herokuapp.com/api/itapetininga-street-last-three-searcheds?access_token=7Z****",
success: function (finalData) {
// Running test
console.log(finalData);
if (finalData) {
// var dd = JSON.parse(result);
// addressStreet(finalData[0].addressStreet)
// name: finalData[0].addressStreet
// Print Results
var options = {
valueNames: ['addressStreet', 'neighborhoodStreet']
};
// Example One
var values = finalData.map(function(finalDatum) {
return {
addressStreet: finalDatum.addressStreet,
neighborhoodStreet: finalDatum.neighborhoodStreet,
};
});
var userList = new List('users', options, values);
// Start Selected Address With Event Delegation
$("#target_ul").on("click", "li", function(event) {
// Prevent Redirect In Click
event.preventDefault();
// Load Options For Notification
var placementFrom = "top";
var placementAlign = "center";
var colorName = "bg-light-green";
// Set Options For Notification
showNotification(colorName, null, placementFrom, placementAlign);
// Start New Notification
function showNotification(colorName, text, placementFrom, placementAlign, animateEnter, animateExit) {
if (colorName === null || colorName === '') { colorName = 'bg-black'; }

$.notify({

// Add Selected Address In Notification
var selectedAddress = $( this ).text();
console.log('Selected address is: ', selectedAddress);
if (event.target && event.target.nodeName === 'LI') {
let item = event.target;
$("#selectedAddress").html(item.innerHTML);
}
// Prepare Input Hidden For Import Data To Form
// Add Informations About Selected Address
$('#selectedSearchAddress').text(selectedAddress);

// Print Variable Contain Native Data From All Street In List
console.log(values);

单击列表后,我的控制台中的响应
elements.js:85 (10)?[{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]
elements.js:189 (10)?[{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]
elements.js:174 Selected address is:
Rua Baltazar Lorenzetto
Jardim Brasil
解决方法:
试试这个
$("#target_ul").on("click", "li", function(event) {
var self = $(this); // Storing the reference of the element
...................... // Your code as is
......................
// Add Selected Address In Notification
var selectedAddress = $( self ).text(); // Using the reference of the stored element
....................... // Your code as is
.......................
