Exit from if block in Javascript

Question

I want to exit from the below if block in Javascript. if I return, then it does not check for the next if condition. How do I do that?

if ($('#id1').length > 0) {

    if(yester_energy == "NaN" || yester_energy == 0){
      //break from #id1
    }

    else{
      //something
    }
    $("#abc").html(somthing)
}

if ($('#id2').length > 0) {

        if(yester_energy == "NaN" || yester_energy == 0){
          //break from #id2
        }

        else{
          //something
        }
}

Super late to the party, but for folks from search, you can use something called labeling. It's not good practice, but in rare cases that can be applied. Basically you can assign a name to the if statement that you want to break from. And anywhere in statement call break from specified name.

Code example:

my_if: if (condition) { 
    // do stuff
    break my_if;
    // not do stuff
}

in your particular case:

id1: if ($('#id1').length > 0) {
    if(yester_energy == "NaN" || yester_energy == 0){
        break id1;
    }else{
      //something
    }
    $("#abc").html(somthing)
}

Even later to the party... Typically in such situations, I use a combination of if and do...while as follows...

if ( condition ) do {

  // processing

  if ( exit_condition ) break;

  // more processing...

} while ( false );

Thus, when the break is encountered, it applies to the do...while loop, and processing continues after the while, effectively breaking out of the outer if statement...
