delphi中控制javascript出现的问题，请大家帮忙
html代码
<input type= "button " onmousedown= "ctlSubmit(event); " name= 'test ' value= "测试 ">
</body>
<Script language= "javascript ">
function chk(uu)
{
alert(uu);
}
function ctlSubmit(event) {
if (event.keyCode == 13) { alert( 'dddd '); }
}
</script>
delphi代码
var
doc:IHTMLDocument2;
all:IHTMLElementCollection;
item:OleVariant;
len,i:integer;
begin
doc:=EmbeddedWB1.Document as IHTMLDocument2;
all := doc.Get_All;
item := all.item( 'test ', 0) as IHTMLElement;
item.onmousedown();
'会提示缺少对象,如果html里用onmousedown= "chk() "就不会，是event这个参数造成的，请问如何解决
[解决办法]
ie不支持event这个对象.
Nascapt的浏览器支持.javascript这个问题应到web栏目去问.
这样改ie支持:
<input type= "button " onmousedown= "ctlSubmit(); " name= 'test ' value= "测试 ">
</body>
<Script language= "javascript ">
function chk(uu)
{
alert(uu);
}
function ctlSubmit() {
if (window.event.keyCode == 13) { alert( 'dddd '); }
}
</script>
