我有一个动态表，并且表中的每一行都有带有UNIQUE ID的删除按钮，我正在做的是单击按钮后的delete单击delete.jsp页面，该页面运行查询以进行删除。我需要的是onlcik传递单击单击以发布按钮的唯一ID，以便查询可以匹配数据库中的ID并删除该行。很抱歉，如果我不太清楚，请查看下面的代码以获取更多说明。任何帮助将不胜感激。
function{
//dynamically generating table which (have rows and one of the columns have buttons to delete)
//each dynamically generated button has unique ID coming from DB
//button is created inside js function
//each table row have buttons with uinqe ID
for eg:
'<input type="button" id="each unique ID from db" class="dingdong">'
}
//now i am using onclick function to delete the row
$(".dingdong").click(function() {
$.post("testdelete.jsp", {
//i need to pass each Unique ID(ID of the button which was clicked) to this post
id
}, function(data) {
});
});
//in testdelet.jsp i have this query
//Delete *from testdb where ID=?最佳答案
在事件监听器中，您可以使用$(this)获得单击的jquery元素：
$(".dingdong").click(function() {
var element = $(this);
var parent = element.parent();
// detach button from dom, so it can't be clicked twice
element.detach();
$.post("testdelete.jsp", {
id: element.attr('id');
}, function(data) {
// on success remove the dom element representing your object.
// I'm guessing you display the data in some sort of table
element.remove();
parent.closest('tr').remove();
});
});
