I created js function and now i want that js function to call itself only once, My code is
function view(str){ $.ajax({ type: "POST", url: '<?php echo base_url()?>index.php/main/'+str+'/', success: function(output_string){ //i want to call function from here only once like view(str); } }); } . How can i do that ? Thanks in advance, Currently it is showing me infinte loop.
Use a flag variable
var myflag = false; function view(str) { $.ajax({ type : "POST", url : '<?php echo base_url()?>index.php/main/' + str + '/', success : function(output_string) { if (!myflag) { view(str); } myflag = true; } }); } Try adding a parameter to the function that keeps track of the count:
function view(str, count) { if (count > 0) { return; } $.ajax({ type: "POST", url: '<?php echo base_url()?>index.php/main/'+str+'/', success: function(output_string) { view(count + 1); // i want to call function from here only once like view(str); } }); } Then you would initially call view like this:
view(str, 0); you are looking for jquery one. http://api.jquery.com/one/
fiddle http://jsfiddle.net/XKYeg/6/
<a href='#' id='lnk'>test</a> $('#lnk').one('click', function view(str) { $.ajax({ type: "POST", url: '<?php echo base_url()?>index.php/main/' + str + '/', success: function (output_string) { i want to call function from here only once like view(str); } }); }); You can pass a bool as a parameter on whether the function should call itself again:
function view(str, shouldCallSelf){ $.ajax({ type: "POST", url: '<?php echo base_url()?>index.php/main/'+str+'/', success: function(output_string){ if (shouldCallSelf) view(output_string, false) } }); } You should call it with true the first time. It will then call itself with false the second time, will not execute again.
