Question:
Silly question I think, but is there a way to use the "if" statement as a reusable function
success: function(msg){ if(msg=='o'){ $j('#ok').show(); $j(button).show(); $j('#chk').hide(); } else{ $j('#ok').hide(); $j('#chk').show(); $j(button).hide(); } } I have a number of times when I want to call it and I would rather have a "smaller" weight.
Solution:1
This technique employs 'closures' to generate a function to provide as a success method:
function doStuffGenerator( button ){ return function( msg ){ if(msg=='o'){ $j('#ok').show(); $j(button).show(); $j('#chk').hide(); } else{ $j('#ok').hide(); $j('#chk').show(); $j(button).hide(); } }; } ... jQuery.ajax({ ... success: doStuffGenerator( button ) ... });
Solution:2
success: function(msg){ doStuff(msg); } function doStuff() { if(msg=='o'){ $j('#ok').show(); $j(button).show(); $j('#chk').hide(); } else{ $j('#ok').hide(); $j('#chk').show(); $j(button).hide(); } }
Solution:3
Sure. Not silly at all.
success: function(msg){ checkMsg( msg ); } ... function checkMsg( msg ) { if(msg=='o'){ $j('#ok').show(); $j(button).show(); $j('#chk').hide(); } else { $j('#ok').hide(); $j('#chk').show(); $j(button).hide(); } } I assume button is a variable that was created outside the scope of the success: callback.
Solution:4
Another way to write functions in jQuery is this:
var myFxn = function(param){ // do function stuff here } var myOtherFxn = function(param){ // do function stuff here } so in your code:
if(msg=='o'){ myFxn(); } else { myOtherFxn(); } Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
