jquery: If statement not working inside ajax success function -


i have success function in ajax returns response text python script can either "success" or "empty". want place if-loop inside success function, if-loop not working. getting correct data python script because alert statement working fine , printing "success". not enter ifloop

i have tried bunch of things control not entering if-loop, please tell me doing wrong:

submithandler: function (form) {                  $.ajax({                     type: 'post',                     url: '/cgi-bin/getdataworld.py',                     data: $(form).serialize(),                      success: function(data) {                             //document.write(result);                             console.log("result "+data);                             alert(data);                              if(data === "success"){                             window.location = 'index.html';                                }                            else{                                  alert("no data present");                                }                       },                      error: function (responsedata) {                 console.log('ajax request not recieved!');             }                  });                  return false;             }

this means you're responding isn't "success". has line break or other whitespace before or after it, maybe more one.

perhaps:

if (/^\s*success\s*$/.test(data)) {     // success }

or use jquery's $.trim:

if ($.trim(data) === "success") {     // success }

also sure you're not replying "success" or "success", string comparisons case-sensitive.

if you're not sure:

if (/^\s*success\s*$/i.test(data)) {     // success }

or

if ($.trim(data).touppercase() === "success") {     // success }

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
