调整步骤的大小，以便所有字段都适合

Question

我试图弄清楚如何根据用户所处的步骤调整背景大小，以便每个步骤的所有字段都会显示。是否可以根据他们所处的步骤来调整大小？我尝试过 css 和 js，但失败了，完全毁了我想要的外观。谁能指导我如何根据他们所处的步骤来调整背景大小？

在 Js 中我尝试添加这样的东西

onStepChanged: function (event, currentIndex, priorIndex)
                {
                    if (currentIndex === 2)
                    {
                        $(".wizard-big.wizard > .content").css("min-height", "530px");
                    }
                },

或者像这样：

onStepChanged: function (event, currentIndex, priorIndex)
                {
                    $(".wizard-big.wizard > .content").css({
                        height: $("#div").height()
                    });
                },

Answer 1

如果我很好地理解你的问题，这是 jquery-steps 的一个老问题。此链接将包含大量信息和解决方案：https://github.com/rstaib/jquery-steps/issues/8#issuecomment-39273777。

我根据该链接的评论制定了自己的解决方案，您可以使用它，我认为它会非常有效，因为它为我工作了一年多。

请执行这些修改：

1.创建一个名为jquery.steps.fix.js的文件。将下面的代码放在上面并在原始jquery.steps.js（或jquery.steps.min.js ）之后加载它。

function resizeJquerySteps() {
     $('.wizard .content').animate({
        height: $('.body.current').outerHeight()
    }, 'slow');
}

$(window).resize($.debounce(250, resizeJquerySteps));

2.您需要替换原始jquery.steps.css的某些部分。

这里（认为是在第 140 行）：

.wizard > .content
{
    background: #eee;
    display: block;
    margin: 0.5em;

    // comment or remove this
    /*min-height: 35em;*/

    overflow: hidden;
    position: relative;
    width: auto;

    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
}

这里（认为是在第 163 行）：

.wizard > .content > .body
{
    float: left;
    position: absolute;
    width: 95%;

    // comment or remove this
    /*height: 95%;*/

    padding: 2.5%;
}

3.现在您需要从插件的事件中准确地调用我们的函数resizeJquerySteps() ，即onInit()、onStepChanging()和onStepChanged()。

onInit: function(event, currentIndex) {
    resizeJquerySteps();
},
onStepChanging: function(event, currentIndex, newIndex) {
    resizeJquerySteps();
},
onStepChanged: function (event, currentIndex, priorIndex) {
    resizeJquerySteps();
}
