用正则将空格给去掉

<input type="text" id="CrmID" name="CrmID" onkeyup="this.value=this.value.replace(/\D/g,'')"
                      onafterpaste="this.value=this.value.replace(/\D/g,'')" 
                      maxlength="12" value="<%:Model.CrmID %>"
                      class="text-box single-line"
                      style="width:108px;" />
