js将格式化后的时间拼接成字符串

<script><span style="font-size:18px;"><span style="font-size:18px;"></span><pre name="code" class="javascript">var str = "2016-04-20 00:00:00";var subStr=str.substring(2,str.length).replace(/-/g,"").replace(/:/g,"").replace(/\s/g, "");<span style="font-size:18px;">substring(2,str.length)//截取根据情况看写不写。replace(/-/g,"")//全局替换"-"replace(/:/g,"")//全局替换":"replace(/\s/g, "")//去掉字符串内所有空格</span></span></script>
