If the select option element in IE6/7/8 does not set the value, the SELECT statement obtains an empty string.

Today, QA reports that the function of changing the number of single pages is unavailable in IE8.

ViewCodeThe select option has no value attribute.

Original code:

<SELECT> <option> 10 </option> <option> 20 </option> <option> 50 </option> </SELECT>

To solve the problem as follows:

<SELECT> <option value = "10"> 10 </option> <option value = "20"> 20 </option> <option value = "50"> 50 </ option> </SELECT>

The specific reason is: when the option element in IE6/7/8 is not set value, select will obtain an empty string.
