如何使用jQuery更改/编辑段落/ div的文本？

现在我要做的是更改/编辑段落和/或div标签的文本。这两个元素都是使用自己的增量ID动态创建的。我希望用户能够在textarea中输入文本，这将改变段落或div的文本。当他们选择段落或div时，textarea应该以用户可以更新文本的方式出现。

Now what I'm trying to do is to change/edit the text of a paragraph and/or a div tag. Both elements are created dynamically with their own incremental id. I want the user to be able to enter a text in a textarea which would change the text of a paragraph or div. When they select the paragraph or div a textarea should appear that way users can update the text.

问题：
因为我在两个元素上都设置了增量ID我很难得到它们。

Problem: Since I have set the incremental ID on both elements its hard for me to get them.

我怎样才能实现这个目标？

How can I achieve this?

这是我的代码我一直在努力

This is the code I've been working on

jQuery：

$(document).ready(function(){

var pid = 1;
$("#addP").on({
    click: function(){
        var pr = $('<p />').attr({'class':'test', 'id':'paragraph_' + pid}).text('This is a paragraph ' + pid);
        var d = $("#Test");
        var pclone = $(pr).clone();
        pclone.on({
            mouseenter: function(){    
                $(this).addClass("inside");
            },
            mouseleave: function(){                             
                $(this).removeClass("inside"); 
            },
                    });
        pclone.appendTo(d);
pid++;
    }
});
var divid = 1;
$("#addDiv").on({
    click: function(){
        var pr = $('<div />').attr({'class':'test', 'id':'div_' +     divid}).text('This is a div ' + divid);
        var d = $("#Test");
        var pclone = $(pr).clone();
        pclone.on({
            mouseenter: function(){    
                $(this).addClass("inside");
            },
            mouseleave: function(){                             
                $(this).removeClass("inside"); 
            },
                    });
        pclone.appendTo(d);
divid++;
    }
});




var div =  $('<div class="customD" id="d"></div>');
var del = $('<a href="#" class="delete" id="erase">Delete</a>');

$('#updateP').hide();
$('#updateD').hide();

var flag = false;
$("#Test").on("click", "p", function(){ 
var cur = $(this).css("background-color");


   if(cur=="rgb(255, 255, 255)") {  
       if(flag==false){
           $('#updateP').show();
            $('#updateD').show();

    $(this).css("background-color","#FDD").addClass("help insider").after(div);
flag = true;

}

}
else { 
 $('#updateP').hide();
 $('#updateD').hide();

            $(this).css("background-color","white").removeClass('help insider');
 $(div).remove();
flag = false;
}    
$(div).append(del);  


$(".delete").on("click",function(){
    $(this).parent().prev().remove();
$(this).remove();
flag = false;

});


}); 

$('#updateP').change(function(){
var a = $(this).val();
$('p').text(a);

});
id++;     
});

HTML：

 <a href="#" id="addP">P tag</a> or <a href="#" id="addDiv">Div   tag</a><br/><br/>
    <textarea id="updateP"></textarea>
    <textarea id="updateD"></textarea>

    <div id="Test"></div>
