Steps步骤条, Bootstrap风格步骤条

 网上看到的Steps的风格并不是我想要的，而且不够简易，所以只能自己写一个(两个版本的Steps)   PS：没发现上传附件在哪，第二个版本就暂时不写了

  

直接上代码

HTML

　　

 <button onclick="addStep()">addStep</button>
    <button onclick="clearSteps()">clearSteps</button>
    <div class="steps">
        <div class="step ">
            <div class="step-head">
                <div class="step-line"></div>
                <div class="step-icon">
                    1
                </div>
            </div>
            <div class="step-main">
                步骤一

    </div>

　　css:

.step {
    position: relative;
    vertical-align: top;
    display: inline-block;
}

.step-head {
    width: 18px;
    height: 18px;

js部分：

    var steps = $(".step");
    var stepIndex = 0;

    setStep(stepIndex);

    $(".step-icon").click(function () {
        var me = this;
        stepIndex = $(me).parents(".step").index();
        setStep(stepIndex);
    });


    function setStep(stepIndex) {
        $(steps).removeClass("is-sucess");
        $(steps).removeClass("last-sucess");

        for (var i = 0; i <= stepIndex; i++) {
            var step = steps[i];
            if (i < stepIndex) {
                $(step).addClass("is-sucess");
            }
            else {
                $(step).addClass("last-sucess");
            }
        }
    }


    function clearSteps() {

 　　 　stepIndex = -1;
　　　 　setStep(stepIndex);

    }


    function addStep(addnum) {
        if (!addnum) { addnum = 1 }
        stepIndex += addnum;
        setStep(stepIndex);
    }
