动态添加html的动画显示

Question

我在任何地方都找不到这个解决方案。

用户进行选择并输入一些值。当他点击添加时，我希望用jQuery添加的html动画(或向下滑动)进入视图。为了设置值，如何检索元素高度？

这就是父级；

<div class="order-summary-wrap"></div>

这段代码可以工作，但是很不协调。

// build the summary boxes from the users inputs
function create_summary(){
    var summary_html = '';

    if( $('.cycle-01').hasClass('cycle-slide-active') ){
        summary_html = '<div class="toll-free-summary-contents remove-me"><p class="line-one"><span class="new-toll-free-number">' + $('.cycle-01 .step-2-container .number').find("option:selected").attr("value") + '</span> in <span class="from-toll-free-country">' + $('.cycle-01 .step-1-container .country').find("option:selected").attr("value") + '</span> will ring to <span class="forward-to-number">' + $('.cycle-01 .step-3-container .country').find("option:selected").attr("value") + '</span> in <span class="to-toll-free-country">' + $('.cycle-01 .step-4-container #ForwardNumberTo').attr("value") + '</span></p><p class="line-two"><span class="toll-free-cost">' + $('.billing-options-hidden').find("option:selected").attr("value") + '</span> (FIRST MONTH FREE) with each minute used costing  <span class="toll-free-per-minute-cost">' + $('.per-minute').text() + '</span></p><div class="remove"><a class="remove-link" href="#">Remove</a><a class="view-link" href="#">View Sample Bill</a></div></div>';
    } else {
        summary_html = '<div class="local-summary-contents remove-me"><p class="line-one"><span class="country-local-number">' + $('.cycle-02 .step-1-container .country').find("option:selected").attr("value") + '</span>  <span class="state-local-number">' + $('.cycle-02 .step-2-container .state').find("option:selected").attr("value") + '</span>  <span class="city-local-number">' + $('.cycle-02 .step-3-container .city').find("option:selected").attr("value") + '</span>  <span class="new-local-number">' + $('.cycle-02 .step-4-container .local').find("option:selected").attr("value") + '</span></p><p class="line-two"><span class="toll-free-cost">' + $('.billing-options-hidden').find("option:selected").attr("value") + '</span> (FIRST MONTH FREE) with each minute used costing  <span class="toll-free-per-minute-cost">' + $('.per-minute').text() + '</span></p><div class="remove"><a class="remove-link" href="#">Remove</a><a class="view-link" href="#">View Sample Bill</a></div></div>';
    }

    $('.order-summary-wrap').append(summary_html);
    $('.add-more-numbers').removeClass('hidden');
}

// click event to dynamically add the summary boxes to the DOM
$('.first-step, .add-number').click(function(e){
    create_summary();
});

此外，当单击"remove“链接时，我希望元素在从DOM中删除时具有动画效果。

// lets the user remove the number from the DOM
$('.order-summary-wrap').on('click', '.remove-link', function(e) {
    e.preventDefault();
    $(this).parent().parent().remove();
});

如果你想滑下的是新的summary_html，你可以这样做。在追加之前隐藏DOM元素，然后在追加后使用.slideDown()使其可见。

下面是一个有效的演示(用更简单的代码来说明)：http://jsfiddle.net/jfriend00/gHcZJ/

并且，这是你实现的代码：

// build the summary boxes from the users inputs
function create_summary(){
    var summary_html = '';

    if( $('.cycle-01').hasClass('cycle-slide-active') ){
        summary_html = $('<div class="toll-free-summary-contents remove-me"><p class="line-one"><span class="new-toll-free-number">' + $('.cycle-01 .step-2-container .number').find("option:selected").attr("value") + '</span> in <span class="from-toll-free-country">' + $('.cycle-01 .step-1-container .country').find("option:selected").attr("value") + '</span> will ring to <span class="forward-to-number">' + $('.cycle-01 .step-3-container .country').find("option:selected").attr("value") + '</span> in <span class="to-toll-free-country">' + $('.cycle-01 .step-4-container #ForwardNumberTo').attr("value") + '</span></p><p class="line-two"><span class="toll-free-cost">' + $('.billing-options-hidden').find("option:selected").attr("value") + '</span> (FIRST MONTH FREE) with each minute used costing  <span class="toll-free-per-minute-cost">' + $('.per-minute').text() + '</span></p><div class="remove"><a class="remove-link" href="#">Remove</a><a class="view-link" href="#">View Sample Bill</a></div></div>');
    } else {
        summary_html = $('<div class="local-summary-contents remove-me"><p class="line-one"><span class="country-local-number">' + $('.cycle-02 .step-1-container .country').find("option:selected").attr("value") + '</span>  <span class="state-local-number">' + $('.cycle-02 .step-2-container .state').find("option:selected").attr("value") + '</span>  <span class="city-local-number">' + $('.cycle-02 .step-3-container .city').find("option:selected").attr("value") + '</span>  <span class="new-local-number">' + $('.cycle-02 .step-4-container .local').find("option:selected").attr("value") + '</span></p><p class="line-two"><span class="toll-free-cost">' + $('.billing-options-hidden').find("option:selected").attr("value") + '</span> (FIRST MONTH FREE) with each minute used costing  <span class="toll-free-per-minute-cost">' + $('.per-minute').text() + '</span></p><div class="remove"><a class="remove-link" href="#">Remove</a><a class="view-link" href="#">View Sample Bill</a></div></div>');
    }
    summary_html.hide();
    $('.order-summary-wrap').append(summary_html);
    summary_html.slideDown();
}

// click event to dynamically add the summary boxes to the DOM
$('.first-step, .add-number').click(function(e){
    create_summary();
});

jfriend00抢先了我一步您可以执行相同的操作来从DOM中删除编号。

$('.order-summary-wrap').on('click', '.remove-link', function(e) {
    e.preventDefault();
    $(this).parent().parent().slideUp().remove();
});
