 $('#form_id').submit(function (e){ var $this = $(this); e.preventDefault(); $.post($this.attr('action'), $this.serialize(), function (responseData) { if(responseData == "success"){ window.location.href = <?php echo (siteurl) ?>; } else if (responseData){ swal({ title: "Error!", text: responseData, type: "error", confirmButtonText: "ok" }); } }); }); 

if i use window.location.href= " http://localhost/abc/abc.php "; it works fine

Answer 1

Change

window.location.href =  <?php echo (siteurl) ?>;

To

window.location.href =  "<?php echo (siteurl) ?>";

You need to wrap the output of the constant in quotes for JS to pick it up as a string (which it requires for a URI)

Answer 2

"'"+<?php echo (siteurl) ?>+"'"

使用它可能会正常工作
