Question

我在ajax中有一个变量，我想发送它onclick事件。这里..

function childID(Obj){
        var replayId = Obj.id;
        // var replayId = '"#'+replayId+'"';
        // console.log(replayId); 
     }

我想保存onlick事件..

$('#allcomments').on("click", replayId, function(){  
     console.log('something action...'); 
 });

这里所有评论都是父ID，而且在loding页面上不会退出重播。

Answer 1

您可以使用Clousures维护状态

＆＃13;

function childID(Obj){
  var replayId = Obj.id;
  // var replayId = '"#'+replayId+'"';
  // console.log(replayId); 
  function outer (id) {
     // id will remain in scope of this function and will be accessable to inner callback
     return function inner () {
      console.log('something action...', id);
     }
  }
  $('#allcomments').on("click", outer(replayId));
  
}

＆＃13;

Answer 2

您正在将变量replayId创建为function childID(Obj)的本地变量。

function childID(Obj) {
  var replayId = Obj.attr('id');
  return replayId;
}

$('input[type=button]').on("click", function() {
  var theID = childID($(this));
  alert(theID);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
  <tr>
    <td><input type="button" id="drink" value="Drink Me"></td>
    <td><input type="button" id="eat" value="Eat Me"></td>
  </tr>
</table>

如果没有更多的代码，很难创建一个强大的答案。我也不完全了解你的困境。 AJAX的目的是不依赖于多个页面来实现功能。除了API调用之类的东西外，所有内容都应该在页面本身上完成。

这是我基于评论系统构建的另一个片段。它在页面上使用了两个函数 - 可以变成一个函数 - 带有注释，返回值以供AJAX使用。

function findCommentID (comment) {
	return comment.parents('li').attr('id');
}

$('#allcomments li li').on('click',function(){
	var commentID = findCommentID($(this))
	var commentAct = $(this).attr('class')
	
	/* Do your AJAX calls here */
	alert(commentID + " " + commentAct)
});

h2 {
  margin-bottom: 0;
  }

p:first-of-type {
  margin-top: 0;
  }
  
ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  }
  
ul ul {
  text-align: right;
  }
  
li li {
  display: inline;
  padding: .5em;
  margin-right: 1em;
  }

li li:hover {
  background-color: #FDD;
  cursor: pointer;
  }
