无需离开原始页面即可发送数据

Question

The watchlistinsert.php sends some information to my database and i want it to send without leaving the original page where i clicked from. I think i need to use some ajax, I have tried a few different things, but it is not working. Hope someone can help me out.

 echo "<td>"."<a id='add' href=\"watchlistinsert.php?symbol=$symbol&price=$price&watchlistgroupid=$watchlistgroupid\">Add</a>"  ."</td>";

You can do this easily with jQuery by using the ajax() function: http://api.jquery.com/jquery.ajax/

Example:

$.ajax({
  url: "/path/to/my/file.php",
  data: {
    'key1': 'value1',
    'key2': 'value2'
  },
  success: function(data, textStatus, jqXHR) {
    // do something
  },
  error: function(jqXHR, textStatus, errorThrown) {
    // do something
  }
})
