javascript - Do nothing on empty input - combinate with dynamic action on form -

what want when type in input, depending button click, change path of action in form. @ half way achieve (i think)....check out make till now

function onsubmitform() {        if(document.pressed == 'log as')        {         document.myform.action ="log-as.html";        }        else        if(document.pressed == 'log int')        {          document.myform.action ="log-as-int.html";        }        return true;      };

<form name="account" onsubmit="return onsubmitform();">    <input type="text" name="user" id="user">    <input type="submit" name="account" onclick="document.pressed=this.value" value="log as" />    <input type="submit" name="account" onclick="document.pressed=this.value" value="log int" />  </form>

and maybe found solution this, don't know how combinate two...

$('#search-form').submit(function(e) {     if (!$('#user').val()) {         e.preventdefault();     }         });

you can same thing using code:

first of name attribute of form , input type submit same. must unique.

<form name="account" id="account" action="">   <input type="text" name="user" id="user">   <input type="submit" name="account_submit1" onclick="document.pressed=this.value" value="log as" />   <input type="submit" name="account_submit2" onclick="document.pressed=this.value" value="log int" /> </form> 

and

   $(document).ready(function () {         $("#account").submit(function(e){             alert($.trim($("#account [type='submit']:focus").val()))             if($.trim($("#account [type='submit']:focus").val()) == "log as"){                 $("#account").attr('action',"log-as.html");                 }else{                 $("#account").attr('action',"log-as-int.html");             }         });     });  

updated code according discussion:

 $(document).ready(function () {         $("#account").submit(function(e){              if (!$('#user').val()) {                e.preventdefault();              }               if($.trim($("#account [type='submit']:focus").val()) == "log as"){                 $("#account").attr('action',"log-as.html");                 }else{                 $("#account").attr('action',"log-as-int.html");             }         });     });
