firefox和innerHTML [英] firefox and innerHTML
问题描述
为什么不是SELECT元素'的innerHTML反映了选择哪个选项是什么？b $ b？适用于IE。我需要这个功能，以便我可以保留用户在选项卡界面中做出的选择。

< blockquote class =post_quotes>为什么SELECT元素'的innerHTML反映哪个选项被选中？
所选属性是指预选，而不是当前是否选择元素
。标记是静态的，并且不会对用户操作的响应进行更改。
我需要此功能以便我可以保留用户所做的选择一个标签式界面。
从对象属性中读取值并稍后重新分配。

你在找什么？选项'的值，选项'的文字或
选项'的选定索引？

为什么不将select对象传递给callAlert函数？

function callAlert（menu）{
alert（menu.options [menu.selectedIndex] .value）;
alert（menu.options [menu.selectedIndex] .text）;
alert（menu.selectedIndex）;

帮助？

使用上述技巧，分配表格名称不是ID。阅读表单元素不涉及
document.getElementById或.innerHTML。请告诉你所有的朋友，让他们告诉他们所有的朋友等。

Why doesn''t a SELECT element''s innerHTML reflected which option was
selected? Works in IE. I need this functionality so that I can retain
what choices a user made in a tabbed interface.

The selected attribute refers to pre-selection, not whether the element
is currently selected. Markup is static and doesn''t change in response
to user actions.
I need this functionality so that I can retain what choices a user
made in a tabbed interface.
Read the values from object properties and reassign them later.

What are you looking for? The option''s value, the option''s text or the
option''s selected index?
[...]
<script language="javascript">
function callAlert(){
var theHTML = document.getElementById(''Radius'').innerHTML;
//alert(theHTML);
}
</script>
Why not pass the select object to the callAlert function?
<script type="text/javascript">
function callAlert(menu){
alert(menu.options[menu.selectedIndex].value);
alert(menu.options[menu.selectedIndex].text);
alert(menu.selectedIndex);
}
</script>
<select onChange="callAlert(this);" id="Radius" name="Radius">
Help?

Using the above technique, assign your form a NAME not an ID. Reading form elements does not involve
document.getElementById or .innerHTML. Please tell all your friends and ask them to tell all their friends etc.
