i have written fallowing function but it’s not working..

<input type="text" onkeyup="isValidDate(this);"/>



    function isValidDate(f){ 
      var regDate = '/^[0-9]*|\/*\|-*|.*$/';
        alert("called::"+f.value);   
      if(!regDate.test(f.value))

        f.value = f.value.replace(regDate,"");  
 }

i am getting an error that-regDate.test is not a function

Title says you’re trying to match date format but your question text says that:

You can try this regular expression:

/^[\d\/\.-]+$/
