Question

我正在尝试使用JQuery填充下拉列表但是像往常一样失败，我可以将数据显示在Div中但不会显示在下拉列表中

我有一个名称 - 数据的选择ID这里是JQuery代码，我在做什么做家伙？

$('input#namein').on('change', function(){

    var name = $('input#namein').val();
    if ($.trim(name) != '') {
        $.post('ajax/name.php', {name: name}, success = function(data) {

            var options = "";

            for(var i = 0; i < data.length; i++)
            {
                options += "<option value='" + data[i].toLowerCase() + "'>" + data[i] + "</option>";            
            }

            $("div#name-data").append(options);

        });


    }

});

HTML：

<html>
    <head></head>
    <body> 
        Service user time Slots:
        <input type="text" id="namein" value="Name"> 
        Time Slots: 
        <form action="times" method=""> 
            <select id="name-data"></select> 
        </form> 
        <script src="js/jquery-1.12.4.min.js"></script> 
        <script src="js/golabl1.js"></script> 
    </body> 
</html>

将此内容添加到您的HTML页面：

<select id="name-data"></select>

您的JavaScript：

var name = $('input#namein').val();if ($.trim(name) != '') {
    $.post('ajax/name.php', {name: name}, success = function(data) {

        var options = "";

        for(var i = 0; i < data.length; i++)
        {
            options += "<option value='" + data[i].toLowerCase() + "'>" + data[i] + "</option>";            
        }

        document.getElementById('name-data').innerHTML = options;

    });

希望这有帮助！

script

因此在加载值之前它已被禁用。然后更改<select id="name-data" disabled="disabled"></select>内的代码，以便在页面加载完成后立即设置选择：

js/golabl1.js

干杯伙计们，我用了

$（document）.ready（function（）{

console.log( "ready!" );

        $.post('ajax/name1.php', success = function(data) {
                if (data != ''){
$('#namein').append(data).show();

}
