Problems with the value of option in select in different browsers

select cannot use php to get the selected value without setting the option value in ie6/7/8. However, in ie9 or above, firefox, and chrome, the value can be obtained whether the value is set or not

For example:

<code><<span>select</span> name=<span>'select_name'>
    <<span>option</span>><span>1</span></<span>option</span>>
    <<span>option</span>><span>2</span></<span>option</span>>
</<span>select</span>>


<<span>select</span> name=<span>'select_name'>
    <<span>option</span> value=<span>'1'>1<span></option></span>
    <<span>option</span> value=<span>'2'>2<span></option></span>
</<span>select</span>>

第一种情况用$_request[<span>'select_name] 在ie6/7/8取到的值为空</span>
第二种情况用$_request[<span>'select_name] 在ie6/7/8可以取到值</span>在其他游览器中则不受影响
</code>

') .addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced the value problem of the option value in select in different browsers, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
