js代码可以写在 href跟事件中

js代码可以写在 href和事件中，javascript :前缀说明是js代码

在IE中默认的都是vbsricpt的,所有javascript的都要加javasript:前缀,要不就报错。

<a href="javascript :history.back(-1);" onClick="javascript :history.back(-1);">返回上一页</a>

<td style="text-align:right;height:27px" valign="top"
           colspan="6">
           <input class="short_button_style"
            onClick="
             javaScript:
             if ( document.getElementById('confirmFlg').value == '1' ) {
              var n = showSaveConfirmMessage();
              if (n == 1) {
               document.applicationListForm.insertAction.value = '1';
               document.applicationListForm.menuId.value = '222';
               document.applicationListForm.submit();
               return false;
              }
              if (n == 2) {
               showDialog();
              }
              if (n == 3) {
               return false;
              }
             }
             showDialog();
