Question

我是JavaScript的最新版本。我遇到了一个问题。请帮忙。

下面是Html代码源，

<BODY onload="initForm(document.frmTKTNetRemitCC)" onkeydown ="bodyOnKeyDown('onSendValidate(document.frmTKTNetRemitCC)')" scroll="no">
<FORM name="frmTKTNetRemitCC">
<TABLE width="100%" BORDER="0">
<TR><TD width="100%">
<FIELDSET>
    <LEGEND class="TITLE">[LABEL id="TITLE_FOP_FARE"]</LEGEND>
    <TABLE width="100%" CELLSPACING="0" CELLPADDING="0" border="0">
    <TR><TD>
        <TABLE width="100%" border="0">
            <!--Form of Payment-->
            <TR>
                <TD width="1px" rowspan="5"></TD>
                <TD id="LBL_NETREMIT_FORMOFPAYMENT" class="LBL" LabelType="MANDATORY" Tooltip="[LABEL id="TIP_NETREMIT_FORMOFPAYMENT"]" width="1%">[LABEL id="LBL_NETREMIT_FORMOFPAYMENT"]</TD>
                <TD><SELECT class="CBO" id="selfop" name="selfop" Tooltip="[LABEL id="TIP_NETREMIT_FORMOFPAYMENT"]" style="width:95px"></SELECT></TD>

下面的JS测试代码源：

function initForm(p_objForm)
{
    try
    {

       alert(document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").Tooltip);
       document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").setAttribute("Tooltip", "Test Tooltip");
       alert(document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").Tooltip);

结果是当警告Tooltip值时，它显示正确的更改。但工具提示值显示仍保持不变。是否需要刷新页面？工具提示属性操作与document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").innerHTML = ?"?

不同

-------更新更多细节

CLASS =＆＃34; LBL＆＃34;

         .LBL { behavior: url([APP id="HTMLROOT"]\AMEX\AX_COMMON\Labels.htc);
    FONT-FAMILY:ARIAL;
    COLOR:BLACK;
    FONT-SIZE:11px;
    FONT-WEIGHT:BOLD;
    }

Label.htc

      <PUBLIC:COMPONENT>
      <PUBLIC:PROPERTY NAME="LabelType" INTERNALNAME="g_vLabelType"/>
       <PUBLIC:PROPERTY NAME="EncoderName" INTERNALNAME="g_vEncoderName"/>
       <PUBLIC:PROPERTY NAME="FieldEncoderPopulate" INTERNALNAME="g_vFieldEncoderPopulate"/>
       <PUBLIC:PROPERTY NAME="ToolTip" INTERNALNAME="g_vToolTip"/>
       <PUBLIC:PROPERTY NAME="DateFormat" INTERNALNAME="g_vDateFormat"/>
       <PUBLIC:PROPERTY NAME="OnFieldEncoderPopulate" INTERNALNAME="g_vOnFieldEncoderPopulate"/>
      <PUBLIC:PROPERTY NAME="isExternalObj" INTERNALNAME="g_vIsExternalObj"/>

g_vTooTip

        function DoInit()
        {
          g_vDocument = document;
          g_vStyle = this.style;
          try
           {
              if(g_vLabelType==null)g_vLabelType="NORMAL";

           }
          catch(e)
          {
           }

           if(g_vToolTip!=null) this.title = g_vToolTip;

           this.className = g_vLabelType;


           }

提前致谢。

在HTML DOM中，它不是ToolTip，而是title。

更改...

alert(document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").Tooltip);
document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").setAttribute("Tooltip", "Test Tooltip");
alert(document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").Tooltip);

要...

alert(document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").title);
document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").setAttribute("title", "Test Tooltip");
alert(document.getElementById("LBL_NETREMIT_FORMOFPAYMENT").title);

为什么更改属性Tooltip内容无效？
