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。当他单击添加时，我希望使用 jQuery 添加的 html 以动画方式（或向下滑动）进入视图。如何检索元素高度以设置值？

这是父母；

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

这段代码有效，但很刺耳。

// 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“删除”链接时，我希望元素在从 DOM 中删除时进行动画处理。

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

如果你想向下滑动的是新的 summary_html，你可以这样做。在添加之前隐藏 DOM 元素，然后在添加后使用.slideDown()使其可见。

这是一个工作演示（用更简单的代码来说明）：http: //jsfiddle.net/jfriend00/gHcZJ/

而且，这是您实现的代码：

// 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 打败了我。您可以从 DOM 中删除数字。

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