JAVASCRIPT经典代码收藏贴

老是忘掉该怎么写~

敲回车键进入下一输入表单项

<script language="javascript">
        function handleEnter (field, event)
        {
         var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
         if (keyCode == 13) {
          var i;
          for (i = 0; i < field.form.elements.length; i++)
           if (field == field.form.elements[i])
            break;
          i = (i + 1) % field.form.elements.length;
          field.form.elements[i].focus();field.form.elements[i].select();
          return false;
         }
         else
          return true;
        }
</script>

<INPUT value="" name="username" onkeypress="return handleEnter(this, event)">

屏蔽所有js错误

<SCRIPT LANGUAGE="JavaScript">
<!-- Hide

function killErrors() {
return true;
}

window.onerror = killErrors;

// -->
</SCRIPT>

模态对话框
<script>

window.showModalDialog("http://www.sohu.com","obj","dialogWidth=500px;dialogHeight=500px;help=no;status=no;scroll=no");
window.history.go(-1);
</script>

跳转表单~根据显示器分辨率重定向网页

<script language="JavaScript" type="text/JavaScript">
<!--
function MM_jumpMenu(targ,selObj,restore){ //v3.0
    eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
    if (restore) selObj.selectedIndex=0;
}
function tiger(){
    if (window.screen.width ==800) eval("parent.location='main1.jsp'");

}
//-->
</script>

select onChange="MM_jumpMenu('parent',this,0)">
<option>::请选择您的目标系统::</option>
<option value="http://172.16.40.7:8080">短消息系统</option>
</select>
