jquery的 运用

多的


 使用 Jquery  插件集合 easyui 中的 弹框 iframe 时，发现附加的 src（即url）之后，页面为空，使用其它的页面时 可以显示， 后来 由经 chrom 中的调试，才发现是 载入的页面中含有 php 的语法错误，导致全部页面都无法显示，想起上次的某些个时候也由此情况，特有此一记，以待后期不犯此错误。

认识 noscript 
					
				
    元素用来定义在脚本未被执行时的替代内容（文本）。
    浏览器如果，无法识别  标签会把标签的内容显示到页面上。<br />
&nbsp; &nbsp; &nbsp;&nbsp;</span><span style="white-space:normal;font-family:Verdana, Arial, Helvetica, sans-serif;background-color:#F9F9F9;">如果识别<span style="line-height:17.98611068725586px;"><script> 标签</span>，那么它不会显示出 noscript 元素中的文本。</span><br style="white-space:normal;" />

				<span style="color:#000000;">&nbsp;密码框设计的时候，最初想法是：</span> 
			</li>
			<li>
				<span style="color:#000000;">&nbsp;&nbsp;&nbsp;&nbsp;触发事件的时候，能够将input的type属性改掉，然后测试下，发现没用，还以为哪里出问题了呢，后来百度了下，原因是 type属性是input的只读属性，改不了的。肯定的是，IE下是不能改的。</span>
