ID を取得: $(this).attr("id");
:使用法ではありません
1. 使用法をリストします
解决方案:
CSS to disable resizing textarea { resize: none; } <textarea <SPAN style="COLOR: #0000ff">name</SPAN>="<SPAN style="COLOR: #8b0000">foo</SPAN>"> textarea[<span style="COLOR: #0000ff">name</span>=foo] { resize: none; } HTML is <textarea id="<SPAN style="COLOR: #8b0000">foo</SPAN>">) #foo { resize: none; }ログイン後にコピー

缺点:
会把正则表达式中类似*/去除
Sample:
value = s.replace(/^0*/, '');
After Compress:
value = s.replace(/^0, '');

有关于$.ajaxSetup和$.get的问题
在Common.js中使用
$.ajaxSetup({ url: "<span style="COLOR: #8b0000">…..</span>", type: "<span style="COLOR: #8b0000">POST</span>", cache: <span style="COLOR: #0000ff">true</span>, dataType: "<span style="COLOR: #8b0000">json</span>" }); $.ajax({ data: { cityCode: cityCode, flag: flag }, success: <span style="COLOR: #0000ff">function</span>(areaList) { …} });ログイン後にコピー在PageA页面引入Common.js
然后在脚本段中使用 $.get(url);
此处url调用的是一个aspx页面,显示结果为无数据加载!(正常情况:有数据加载。)
然后经过使用IE8的开发人员工具,进行Trace Error.最终发现原因错误信息(如下)
"Invalid JSON:
那么如何解决呢?
原因:
肯定是请求数据类型有问题?
解决方案:
1.在Page A 页面脚本段 $.get(url,“html”);
因为$.get中的Data是可选项,现在确定原因之后,我们就来预定义好DataType
结果:OK
分析源由:
是因为$.ajaxSetup是用全局设定的,所以全局已经设定了DataType:JSON了。
那Page A 页面的$.get()肯定受及影响。
最终解决方案:
改Common.js,去掉ajaxSetup全局设定
$.ajax({ url: "…..", type: "POST", cache: true, dataType: "json",data: { cityCode: cityCode, flag: flag }, success: function(areaList) { …} });
结果:OK
