Question

我正在利用随机用户员工目录API使用AJAX / jQuery构建员工目录。这是我使用的实际数据Feed：

https://randomuser.me/api/?results=12&format=json

我已经成功检索并显示了一个充满样本员工的页面。但是如果用户点击记录，我在显示个人记录（通过模式）方面存在问题。 Console log正在说"Cannot read property 'cell' of undefined"。我非常有信心这是因为displayModal函数无法访问'employees'变量中json调用的数据。我已尝试在$ajax电话中移动该功能，我会检索数据，但这不起作用 - 所以不确定从何处开始。

//Get JSON DATA and stored data in variable Employees.
var employees;

$.ajax({
    url: 'https://randomuser.me/api/?results=12&format=json',

    success: function(data){
        employees = data.results;
        displayEmployees(employees);
        console.log(employees);
    }
});

//Create Function to Build Employee Car
function displayEmployees(employees){
    var employeesHTML = ""
    $.each(employees, function(i, employee) {
        employeesHTML += '<div class="employee" employee-id="' + employee.id.value + '>';
        employeesHTML += '<a href="">';
        employeesHTML += '<img class="employee-photo" src="' + employee.picture.large + '"></a>';
        employeesHTML += '<div class="info">';
        employeesHTML += '<div class="name">'+ employee.name.first + ' ' + employee.name.last + '</div>';
        employeesHTML += '<div class="email grey-font">'+ employee.email + '</div>';
        employeesHTML += '<div class="city grey-font">' + employee.location.city + '</div></div></div>';
           });

    $('.employees').html(employeesHTML);

};

//Create Function to Build Modal
function displayModal(employees, id){
    var employeesModal;
    //create modal
    employeesModal += '<div>' + employees[id].cell + '</div';

    $('.modal-text').html(employeesModal);

}

//Click Event To Display Modal
var modal = document.getElementById('myModal');
$('.employees').on("click", ".employee", function() {
    $.each(employees, function(i, employee) {
        var id = $(this).attr('employee-id');
        modal.style.display = "block";
        displayModal(employees, id);
        console.log('click');
    });
});

// // When the user clicks on (x), close the modal
$('.close').on("click", function() {
    modal.style.display = "none";
});

// // When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}


console.log(employees);

试试这个。

//Get JSON DATA and stored data in variable Employees.
var employees;

$.ajax({
    url: 'https://randomuser.me/api/?results=12&format=json',
    success: function(data){
    	employees = data.results;
    	displayEmployees(employees);
	}
});
//Create Function to Build Employee Car
function displayEmployees(employees){
	var employeesHTML = ""
	$.each(employees, function(i, employee) {
		employeesHTML += '<div class="employee">';
	    employeesHTML += '<a href="">';
	    employeesHTML += '<img class="employee-photo" src="' + employee.picture.large + '"></a>';
	    employeesHTML += '<div class="info">';
	    employeesHTML += '<div class="name">'+ employee.name.first + ' ' + employee.name.last + '</div>';
	    employeesHTML += '<div class="email grey-font">'+ employee.email + '</div>';
	    employeesHTML += '<div class="city grey-font">' + employee.location.city + '</div></div></div>';
	       });

    $('.employees').html(employeesHTML);

};

//Create Function to Build Modal
function displayModal(employees){

	//create modal
    employeesModal += '<div>' + $(employees).html() + '</div>';

只需修改css即可正确显示。
