在开发中遇到了一个问题,使用js一直获取不到dom元素..找了很久终于找到一个可行的方案:
代码如下:
<script id='tpl_order_index_list' type='text/html'>
<%each list as order%>
<div class='fui-list-group order-item' data-orderid="<%order.id%>" data-verifycode="<%order.verifycode%>">
<div class='fui-list-group-title lineblock2 '>
订单号: <%order.ordersn%>
<span class='status <%order.statuscss%>'><%order.statusstr%></span>
</div>
<%each order.goods[0].goods as g%>
<div class="fui-list goods-list">
<a class="good-box" href="{php echo mobileUrl('order/detail')}&id=<%order.id%>" data-nocache='true'>
<div class="fui-list-media" style="<%if g.status==2%><%/if%>">

</div>
<div class="fui-list-inner">

<script type='text/javascript'>
function design(current) {
var diyUrl = $(current).data('url'),
diyType = $(current).data('diytype'),

otherParam = diyType > 0 ? ('-ver='+ (diyType*1 + 1)): '',

复制代码原因:
<script type="text/html" id="javascript_template">
复制代码在模板渲染时js已经全部执行完了,导致js获取不到dom元素...
这种写法，在页面渲染的时候，浏览器不会读取script标签中的html代码, 外面不能获取到里面的div节点
所以： 在使用时，要在script标签上加个ID可以供我们找到它， 即然做模版用，且里面的html代码不会被渲染读取，则需在外面再新建一个div来当容器，装下这些html代码， 即我们可以通过
var _html=document.getElementById('javascript_template').innerHTML;
document.getElementsByTagName('div')[0].innerHTML=_html;
复制代码然后我们模版里的htmll代码就可以运行在页面中了;
解决:
如果遇到html代码加入外部div后，获取不到节点的情况，可以在外部写个函数，然后在html内部用行内调用 οnclick="_dom()"
function _dom() {
document.getElementById('wrap')
}
