在网页上使用<SCRIPT src="xxx.js">就提示找不到对象，把xxx.js里的内容都写到网页上就没有问题！

Question

指明是JS还是VBS看看<SCRIPT language="" src="xxx.js">

Answer 1

如下:
//city.js/* -------------------- MANAULS --------------------
ver 1.0
by itsuki 


// 2 arguments
setProvinceCity (objProvince, valProvince);
// 3 arguments
setProvinceCity (objCity, valProvince, valCity);
// 4 arguments
setProvinceCity (objProvince, objCity, valProvince, valCity);

}
}以上是一个js文件，html里面是这样的<SELECT id="province" style="WIDTH: 120px" onchange="setProvinceCity(document.all.city,this.options[this.selectedIndex].value,'');"
name="province">
<OPTION value="" selected>loading ......</OPTION>
</SELECT>
<SELECT id="city" style="WIDTH: 120px" name="city">
<OPTION value="" selected>loading ......</OPTION>
</SELECT>
<script language="JavaScript">setProvinceCity(document.all.province,document.all.city,"","");</script>如果在html里面用<script language=javascript src=city.js></script>那么就会出错，如果直接把上面的js内容都放在html页面里面就没有问题。。

Answer 2

<script language="JavaScript">setProvinceCity(document.all.province,document.all.city,"","");</script> 这行 提示缺少对象

Answer 3

<script defer>setProvinceCity(document.all.province,document.all.city,"","");</script>

Answer 4

等效的写法是
<script language="JavaScript">
setTimeout('setProvinceCity(document.all.province,document.all.city,"","");',0);
</script>

Answer 5

如果JS里面的函数会在加载网页时执行，就不能放在JS文件里！
