如何在jquery中的for循环中为id添加一个数字？

Question

我希望重现大量点击功能，无需复制并将它们一直粘贴到页面上，然后更改单个数字。我的问题是我无法在我的for循环中更改ID。

这是我的剧本：

for (var i=0;i<$('.slide').length;i++) {
            $step = $('#step'+i);
            $step.on('click', slideTo);
            function slideTo(event){
                $(this).off('click');
                $active = $('.current');
                if (!$active.is('#slide'+i)) {
                    $active.animate({
                        left: '-1024px'
                    }, 500, function() {
                        $(this).removeClass('current');
                    });
                    $('#slide'+i).animate({
                        left: '0'
                    }, 500, function() {
                        $(this).addClass('current');
                        $step.on('click', slideTo);
                    }).addClass('current');
                };
            };
        }

有很多HTML，但现在有一点点：

<div id="slider" class="article">
            <div id="slideHolder">
                <!-- Step 1 -->  
                <div class="walkthrough firstClass current">
                    <div class="step">
                        <h4>STEP 1: Go to the DRMA Service Center.</h4><p>From the RII Homepage <a href="http://r2.nrc.gov" target="_blank" title="">(r2.nrc.gov,)</a> Look under where it says Quicklinks. The second link from the top of the list is the link to the DRMA Service Center. You can click there or click the link below the image to the right. >>></p>
                    </div>
                    <div class="stepImg">
                        <img src="img/step1.jpg" alt="" />
                        <a href="" title="">Think you got it? Exit to the DRMA Service Center >>></a>
                    </div>
                    <div class="clr"></div>
                </div>
    <!-- Step 2 -->         
                <div class="walkthrough">
                    <div class="step">
                        <h4>STEP 2: LOGIN.</h4><p>Here you want to log in just as you would to your Region II workstation.<br /><br />Username: Your LAN ID<br />Password: Your regular NRC Password</p>
                    </div>
                    <div class="stepImg">
                        <img src="img/step2.jpg" alt="" />
                        <a href="" title="">Think you got it? Exit to the DRMA Service Center >>></a>
                    </div>
                    <div class="clr"></div>
                </div>
</div>
</div>
        <div id="sliderControls">
            <div class="slide" id="step1">Step 1</div>
            <div class="slide" id="step2">Step 2</div>
</div>
