以下代码允许我将新内容附加到div“用户”。但是,如果用户单击按钮,我希望能够删除附加的内容。
当前代码在单击时仅删除“删除”按钮。但是,我需要在附加代码的开头删除带有“ removeuser”类的整个附加代码。
任何帮助将不胜感激!
<div id="users"></div>
<script>
function adduser() {
count += 1;
$('#users').append('<div id="field'+ count +'" class="removeuser[]"><div
id="left"><div id="fieldname">user #'+ count +' Name:</div><div
id="field"><input id="user_name'+ count +'" name="user_name[]"' + '"
type="text" /></input></div><div id="clear"></div></div><div id="leftleft">
<div id="fieldname">user #'+ count +' Age</div><div id="field"><input
type="number" id="user_age'+ count +'" name="user_age[]"
style="width:50px;" min="0"></input></div><div id="clear"></div><br></div>
<div id="leftleft"><a href="javascript: void(0)" onclick="adduser(); return
false;"><div id="field" class="add"><div
style="position:relative;left:-4px;top:1px;">add another user +</div></div>
</a><br></div> <div id="leftleft"><a href="javascript: void(0)"
onclick="$(this).remove();" ><div id="deluser[]" class="add"><div
style="position:relative;left:-4px;top:1px;">-</div></div></a><br></div>
<div id="clear"></div></div>');
var no = document.getElementById("deluser");
no.onclick = function(){
$('#users .removeuser').$(this).remove();
};
</script>

使用类似的东西
$( '#users' ).empty();
答案 1 :(得分:0)
您需要使用以下代码
var no = $(".deluser"); // add class 'deluser' to each div
no.onclick = function(){
$('#users').empty();
};

据我所知,这可能是您正在寻找的解决方案(注意,并非所有浏览器都支持。请参见下面的编译版本) ...
var count = 0;
adduser();
function adduser() {
$('#users').append(newUser(count))
count++;
}
function deluser(e) {
$(e.target).closest('.user-container').remove();
}
function newUser(count) {
var deleteButton = `
<div>
<a href="javascript: void(0)" onclick="deluser(event); return false;">
<div class="add delete-user" data>
<div style="position:relative;left:-4px;top:1px;">-</div>
</div>
</a>
<br>
</div>
`;
return `
<div class="user-container">
<div id="left">
<div class="fieldname">
user #${count} Name:
</div>
<div class="field">
<input id="user_name${count}" name="user_name[]" type="text" /></input>
</div>
<div id="clear"></div>
</div>
<div>
<div class="fieldname">
user #${count} Age
</div>
<div class="field">
<input type="number" id="user_age${count}" name="user_age[]" style="width:50px;" min="0"></input>
</div>
<div id="clear"></div><br>
</div>
<div>
<a href="javascript: void(0)" onclick="adduser(); return false;">
<div class="field" class="add">
<div style="position:relative;left:-4px;top:1px;">add another user +</div>
</div>
</a>
<br>
</div>
${count > 0 ? deleteButton : ""}
<div class="clear">
</div>
</div>
`;

尽管您的初次尝试有很多地方出了问题,但我并不表示无礼,但是您可能应该做更多的工作来学习HTML,JS和jQuery的基础知识。 Treehouse是我很多年前开始的地方,并认为它是Web开发(Treehouse - front-end web development)的出色入门。话虽这么说是最明显的问题...
id
s
id
属性必须唯一。与之类似,具有id="leftleft"
然后在同一文档中具有id="leftleft"
的另一个元素上是无效的。}
的右括号这是通过Babel编译代码后的外观,所有浏览器都支持该代码。
var count = 0;
adduser();
function adduser() {
$('#users').append(newUser(count));
count++;
}
function deluser(e) {
$(e.target).closest('.user-container').remove();
}
function newUser(count) {
var deleteButton = "\n <div>\n <a href=\"javascript: void(0)\" onclick=\"deluser(event); return false;\">\n <div class=\"add delete-user\" data>\n <div style=\"position:relative;left:-4px;top:1px;\">-</div>\n </div>\n </a>\n <br>\n </div>\n ";
return "\n <div class=\"user-container\">\n <div id=\"left\">\n <div class=\"fieldname\">\n user #".concat(count, " Name:\n </div>\n <div class=\"field\">\n <input id=\"user_name").concat(count, "\" name=\"user_name[]\" type=\"text\" /></input>\n </div>\n <div id=\"clear\"></div>\n </div>\n <div>\n <div class=\"fieldname\">\n user #").concat(count, " Age\n </div>\n <div class=\"field\">\n <input type=\"number\" id=\"user_age").concat(count, "\" name=\"user_age[]\" style=\"width:50px;\" min=\"0\"></input>\n </div>\n <div id=\"clear\"></div><br>\n </div>\n <div>\n <a href=\"javascript: void(0)\" onclick=\"adduser(); return false;\">\n <div class=\"field\" class=\"add\">\n <div style=\"position:relative;left:-4px;top:1px;\">add another user +</div>\n </div> \n </a>\n <br>\n </div> \n ").concat(count > 0 ? deleteButton : "", "\n <div class=\"clear\">\n </div>\n </div>\n ");

我试图用另一种方式说明您的方法,希望对您有所帮助。
var count = 0;
function addUser(i) {
var userBloc = '<li class="list-group-item" id="user'+i+'"> I am the user'+ i +
' <br><button class="btn btn-danger remove" data-count="'+i+'">Remove me</button><hr></li>';
return userBloc;
}
$('#add').click(function(){
$('#blocs').append(addUser(count));
$('#user'+count).fadeIn(activeRemove); //important to active remove event
count++;
});
function activeRemove(){
$.each($('button.remove'), function(i,item){
$(item).click(function(){
$('#user'+$(item).attr('data-count')).remove();
});
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="blocs" class="list-group"></div>
<button id="add">Add a another user</button>
