• try this javascript:validate(); – Sumit Bijvani Commented Mar 13, 2013 at 11:30
• @Sumit yes,i have made validate(); , but the problem is that script doesn't call that function – Dev Commented Mar 13, 2013 at 11:32
• @SumitBijvani the prefix javascript: in on… attributes is a mistake. It's never needed, it doesn't do anything (it doesn't cause syntax error only because it happens to match break/continue labels syntax) – Kornel Commented Mar 13, 2013 at 11:35
• can you please write the code here for function validate() – Praveen kalal Commented Mar 13, 2013 at 11:45

Maybe you could try this

<form method="get" name="f1" id="f1" class="formular" action="findcars.php" onsubmit="myFunction(); return false;">

<script>
    myFunction function () {
    validate(); 
    showLocation();
}
</script>

try doing

validate() && showLocation();

or, calling one master function which then runs a chain:

masterFunction();

function masterFunction() {
  validate();
  showLocation();
}

Try this

<form method="get" name="f1" id="f1" class="formular" action="findcars.php" onsubmit="validate(); showLocation(); return false;">  
    <button id="search-submit" type="submit">Search</button>
</form>

Javascript

function validate(){
    alert('validate');
}
function showLocation(){
    alert('Location');
}

do in this way..

<form method="get" name="f1" id="f1" class="formular" action="findcars.php" onsubmit="return myvalidations();">

function myvalidations() {
validate(); 
showLocation();
}

Arrange functions like this:

<input type="button" onclick="function1();function2();" value="Call2Functions" />

  function func1(){
     //--- some logic
     func2();
   }

   function func2(){
    //--- some logic
   }

First call only validate() method if return true then call second method inside it. like below

function validate(){
// ok is output of your validate method whether true or false
if(ok){
showLocation();
}
else{
return false;
}
}
