dialogArguments只能在mode和modeless窗口中才能使用，可以传递传递任意类型的值， 上例就是传得失window. 在以前的项目中，页面之间传递参数经常使用的是url后接参数的形式， 现在终于发现dialogArguments不愧为更好的方法。
<HTML> <HEAD> <TITLE>showModelessDialogEX.htm</TITLE> <SCRIPT> var sUserName=""; function fnCallDialog(){ showModelessDialog("myDialog.htm",window,"status:false;dialogWidth:300px;dialogHeight:300px"); } function fnUpdate(){ oName.innerText = sUserName; } </SCRIPT> </HEAD><BODY> <P>Enter your first name: <SPAN ID="oName" STYLE="color:red;font-size:24">Joan</SPAN></P> <INPUT TYPE="button" VALUE="Display Modeless Dialog" onclick="fnCallDialog()"> </BODY> </HTML>
Here is the code for "myDialog.htm".
<HTML>
<HEAD>
<TITLE>myDialog.htm</TITLE>
<SCRIPT>
function fnGetInfo() {
var sData = dialogArguments;
sData.sUserName = oEnterName.value;
sData.fnUpdate();
}
function fnCancel() {
var sData = dialogArguments;
sData.sUserName = "Joan";
sData.fnUpdate();
}
</SCRIPT>
</HEAD>
<BODY>
<LABEL FOR="oEnterName" ACCESSKEY="f">
Enter your <SPAN STYLE="text-decoration:underline">F</SPAN>irst Name</LABEL>
<INPUT ID=oEnterName><BR><BR>
<INPUT VALUE="Apply" TYPE=button onclick="fnGetInfo();">
<INPUT VALUE="Ok" TYPE=button onclick="fnGetInfo();window.close();">
<INPUT VALUE="Cancel" TYPE=button onclick="fnCancel();window.close();">
</BODY>
</HTML>
