表单填写时用回车代替TAB的实现方法_表单特效

其次，在每一个表单元素中设定一个tabindex值，假定该表单有三个元素，则我们分别设定tabindex值如下：


<p>最后，写出changefocus函数如下： <BR>function newinfo_form_onkeyup() <BR>{ <BR>key=window.event.keyCode; <BR>if(key==0xD)//判断是否按下回车键 <BR>{ <BR>CurTabIndex=event.srcElement.tabIndex 1//将当前tabindex的值加1 <BR>for (n=0;n<newinfo_form.elements.length;n ) <BR>{ <BR>if (newinfo_form.elements[n].tabIndex==CurTabIndex) //找到下一个表单元素 <BR>{ <BR>newinfo_form.elements[n].focus(); //移动焦点 <BR>return true; <BR>} <BR>} <BR>} <BR>} </p><p><script type="text/javascript" src="https://jss.51dongshi.net/pcwz/dysph.js"></script></div> <div class="downbox clearfix"> <div class="ico"><img src="https://js.51dongshi.net/tpl/pc2/images/document.png" alt="文档"></div> <div class="txt"> <h4>表单填写时用回车代替TAB的实现方法_表单特效</h4> <div class="co">表单填写时用回车代替TAB的实现方法_表单特效:关键之处在于tabindex，其设计思想是：为每个表单元素设置一个tabindex，其值分别为前一个表单元素的tabindex的值加一，函数的功能就是当用户按下回车键时先将当前tabindex的值加一，而后逐一与每个表单元素的tabindex值进行对比，如若相等，则将焦点移至该</div> <div class="tj"><b>推荐度：</b><div class="tj_stars_list"><i class="tj_stars tj_05"></i></div></div> </div> <div class="btn"> <a href="javascript:;" class="html2word" data-model="article" data-id="ahbsra" title="文档下载"> <b>点击下载本文</b> <span>文档为doc格式</span> </a> </div> </div> <script>keji_detail_ga('article_content_bottom');</script> <div class="tvideo_tag"> 标签： <a href="/tlist-57953/">实现</a> <a href="/tlist-173669/">表单</a> <a href="/tlist-319868/">回车</a> </div> <div class="tvideo_box tvideo_box_tab"> <div class="hd"> <ul><li class="on">热门焦点</li><script>keji_detail_ga('hot_jiaodian_tab_title');</script></ul> </div> <div class="bd"> <ul class="ult_jpic clearfix"> <script>get_hot_jiaodian_content('wz_hot_jiaodian',33,'hot',1);</script> </ul> </div> </div> </div> <!--中间文章 end--> <!--右侧专题 star--> <div class="ult_zt"> <script>keji_detail_ga('article_right_top');</script> <div class="ult_ztbox"> <h4>最新推荐</h4> <ul class="tvideo_r_a clearfix"> <script>get_detail_right('wz_right_new',33,'')</script> </ul> </div> <script>keji_detail_ga('article_right_middle');</script> <div class="ult_ztbox"> <h4>猜你喜欢</h4> <ul class="telist_rb clearfix"> <script>get_detail_right('wz_right_love',33,'')</script> </ul> </div> <script>keji_detail_ga('article_right_new_bottom');</script> <div class="ult_ztbox"> <h4>热门推荐</h4> <ul class="tvideo_r_b clearfix"> <script>get_detail_right('wz_right_hot',33,'')</script> </ul> </div> <script>keji_detail_ga('article_right_bottom');</script> </div> <!--右侧专题 end--> <div style="display:none"><a href="https://www.51dongshi.net/wzztf/ah/ahbsra/">专题</a> </div> </div> </div> <script src="https://js.51dongshi.net/plug/qrcode/qrcode.min.js"></script> <script src="https://js.51dongshi.net/js/share.js" charset="UTF-8"></script> <script type="text/javascript" src="https://js.51dongshi.net/tpl/pc2/js/waypoints.min.js"></script> <script type="text/javascript" src="https://js.51dongshi.net/tpl/pc2/js/icon_step.js"></script> <style> #qrcode{padding: 15px;background: #fff;} </style> <div id="qrcode" style="display: none"></div> <script>new QRCode(document.getElementById("qrcode"), "https://m.51dongshi.net/eedfahbsra.html");</script> <iframe src="https://hits.51dongshi.net/?biao=ho_article&id=956319" border="0" frameborder="0" style="width: 0px;
