如何使用两个$ .post方法 [英] how to use two $.post methods very well

问题描述

 function ChangeGallery(){
    var GalleryName = $('.SubSubGalleryLock').text();

    /*Send string to Data1.php and include Tags from Database*/
    $.post("Data1.php", {  Sections: GalleryName  },
    function(data){
         $(".IncludeData").append(data);
    }); 

    /*send string to Data2.php and include Events data from Database*/
    $.post("Data2.php",{  GallerySec: GalleryName  },
    function(response){
         /*when i use alert method, this function works very well, why?*/
         alert('SomeString');
     var data = jQuery.parseJSON(response);
         var ImageID  = data[0];
         var ImageSrc = data[1];
     $(ImageID).click(function(){
        $(".LargeImage").attr('src', ImageSrc);
     });
     });
};

在Data1.php中

in Data1.php

  /*give data from database1 and print to HTML File*/
  if ($_POST['Sections']) == "String")
  {  $results = mysql_query("SELECT * FROM Table1");
  while($row = mysql_fetch_array($results))
  { echo $row['Tags']; }

in Data2.php

  /*give data from database2 and Use for events*/
  if ($_POST['GallerySec']) == "String")
  {  $results = mysql_query("SELECT * FROM Table2");
  while($row = mysql_fetch_array($results))
  { echo json_encode($row); }

然后Data1.php工作得非常好，但Data2.php只在我写了一个警报（'Some stringh'）; var data = jQuery.parseJSON（response）;行，它工作得很好，为什么？是什么导致了这个问题？你可以​​在这个页面上看到它 http：//www.3dcreate。 ir / Pages / Gallery / GalleryShow.php

in Client side when i use it then Data1.php works very well but Data2.php only when i write an alert('Some stringh'); after var data = jQuery.parseJSON(response); line, it's work well, why? what's due to this problem?you can see it in this page http://www.3dcreate.ir/Pages/Gallery/GalleryShow.php

推荐答案

jQuery不会绑定到添加到DOM的新元素被调用之后，除非你在被添加后重新绑定或者最初绑定到父元素：

jQuery won't bind to new elements added to the DOM after being called unless you rebind after they've been added or you bind to the parent element initially:

$("#Chosen_Div-parent").on("mouseover", ".Chosen_Div", function(event){
  //Some codes
});

（如果你有多个 Chosen_Div 元素，使用类来代替id）

(If you're ever going to have more than one Chosen_Div element, use classes instead of ids)
