<input class="m-form-control" onpaste="return false" placeholder="直播间名称" 
name="name" onkeyup="this.value=this.value.replace(/[^\u4e00-\u9fa5|\u0000-\u00ff|\u3002|\uFF1F|
\uFF01|\uff0c|\u3001|\uff1b|\uff1a|\u3008-\u300f|\u2018|\u2019|\u201c|\u201d|\uff08|\uff09|\u2014|\u2026|\u2013|\uff0e]/g,&#39;&#39;)" 
onafterpaste="this.value=this.value.replace(/[^\u4e00-\u9fa5|\u0000-\u00ff|\u3002|\uFF1F|\uFF01|\uff0c|\u3001|
\uff1b|\uff1a|\u3008-\u300f|\u2018|\u2019|\u201c|
\u201d|\uff08|\uff09|\u2014|\u2026|\u2013|\uff0e]/g,&#39;&#39;)">
