javascript window.open failing to open in same browser window

Question

I am trying to open a web page in the same window after validating user ID. The html/javascript code is:

 <script language="javascript">
function check(form)/*function to check userid & password*/
{
 if(form.loginID.value == "" && form.loginPass.value == "") {
 window.open("mform.html","_self"); 
}
else {
 alert("Error Password or Username") 
 }
 }
 </script> 
 </body>

If I use _self the browser just reloads original page. If I change it to _blank it opens a new window with the correct page loaded. I have tried this in Safari, firefox and chrome browsers with the same results.

Any assistance is appreciated.

Answer 1

window.open is used to open a new window.

Use window.location.href = 'mform.html' to navigating the other URL in the same window.

• user2026696: I changed per your recommendations. Now works in firefox and chrome but not safari. In safari it still just reloads original page(index.html).
• Yair Nevet: when do you call check(form)?
• user2026696: I found the fix for Safari. The original html code was "<input type="submit" name="submit" value="Login" onClick="check(this.form)"/>". I changed it to "<input type="submit" name="submit" value="Login" onClick="check(this.form);return(false)"/>" now the code works in all browsers. Yair thank you for your recommendation. It got me to the results.
