Question

所以，再次，我是JQuery的新手，但无论出于何种原因，单击“添加场景”按钮时JQuery不会附加表单。它甚至没有涉及#add的功能。我在.on（）行上设置了一个断点，当我点击它时似乎没有识别它。

$(document).ready(function ()
{
    $('#add').on('submit',function(e)
    {
        var form = "<div class='form'>\
        <h3> Scenario </h3>\
        <form id='scenario'>\
            <div>Name: <input type='text' name='ScenarioName'> </div>\
            <div>Rate of Investment Return (While Working): <input type='number' name='Working'></div>\
            <div>Rate of Investment Return (Retired): <input type='number' name='Retired'></div>\
            <div>Desired Retirement Yearly Income: <input type='number' name='desiredInc'></div>\
            <div><input type='submit' value='Submit'></div>\
        </form>\
        <div><button id='add' type='submit'>Add Scenario </button></div>\
    </div>"
        $('body').append($(form));
        e.preventDefault();
    });
});

<body>
    <div class='form'>
        <h3> Basic Information </h3>
        <form id='basic'>
            <div>Year of Birth: <input type='number' name='YOB'> </div> 
            <div>Current Savings: <input type='number' name='CurrSav'> 
            </div>  
            <div>Expected Retirement Age: <input type='number' name='RetAge'></div>     
            <div>Life expectancy: <input type='number' name='LifeExp'>
            </div>  
            <div><input type='submit' value='Submit'></div> 
        </form>
    </div>
    <div class='form'>
        <h3> Scenario </h3>
        <form id='scenario'>
            <div>Name: <input type='text' name='ScenarioName'> </div>
            <div>Rate of Investment Return (While Working): <input type='number' name='Working'></div>
            <div>Rate of Investment Return (Retired): <input type='number' name='Retired'></div>
            <div>Desired Retirement Yearly Income: <input type='number' name='desiredInc'></div>
            <div><input type='submit' value='Submit'></div>
        </form>
        <div><button id='add' type='submit'>Add Scenario </button></div>
    </div>
</body>

Answer 1

而不是submit event处理程序，你需要使用click event处理程序 - 提交事件是表单元素，你正在注册按钮元素的处理程序。

$(document).ready(function () {
    $('#add').on('click', function (e) {
        var form = "<div class='form'>\
        <h3> Scenario </h3>\
        <form id='scenario'>\
            <div>Name: <input type='text' name='ScenarioName'> </div>\
            <div>Rate of Investment Return (While Working): <input type='number' name='Working'></div>\
            <div>Rate of Investment Return (Retired): <input type='number' name='Retired'></div>\
            <div>Desired Retirement Yearly Income: <input type='number' name='desiredInc'></div>\
            <div><input type='submit' value='Submit'></div>\
        </form>\
    </div>";
        $(this).parent().before(form)
        e.preventDefault();
    });
});

Answer 2

试试这个：

$('#add').on('click', function(e) // <-- click instead of submit
    {
        var form = "<div class='form'>\
        <h3> Scenario </h3>\
        <form id='scenario'>\
            <div>Name: <input type='text' name='ScenarioName'> </div>\
            <div>Rate of Investment Return (While Working): <input type='number' name='Working'></div>\
            <div>Rate of Investment Return (Retired): <input type='number' name='Retired'></div>\
            <div>Desired Retirement Yearly Income: <input type='number' name='desiredInc'></div>\
            <div><input type='submit' value='Submit'></div>\
        </form>\
        <div><button id='add' type='submit'>Add Scenario </button></div>\
    </div>";
        $('body').append(form); // no need to wrapping with jQuery
    });

Answer 3

您的点击事件处理程序错误。

当用户尝试提交表单时，submit事件将发送到元素。它只能附加到form元素。

更改此

 $('#add').on('submit',function(e)

为：

$('#add').on('click',function(e)

JQuery没有附加html表单
