BackgroundCode:
// Define a global bool variable ^-^ <br/> protected bool isuser = false;
Front-end:
$ (Document ). ready (function () {<br/> // $ ("# Language "). change (function () {<br/> // var lang = $ ("# Language "). val (); <br/> // location. href = "default. aspx? Writelanguager = "+ <br/> //}); </P> <p> // access the global bool variable in the background <br/> If (<% = This. isuser. tostring (). tolower () %>) <br/>{</P> <p >}< br/> else <br/>{< br/> $ ("# myaskbut "). hide (); <br/>}</P> <p> var def = "<option value =''> select </option> "; </P> <p> $ ("# Language "). prepend (DEF); <br/> $ ("# Language "). val (""); <br/> });
In fact, I just want to say that if the isuse variable value in the background is directly in the foreground <% = this. isuser %>
If the actual value is false (or true), it cannot be used as the basis for the if condition judgment and must be converted
False (or true) ^-^
