当我尝试添加第一个联系人并提交它时,它将显示在div id = contact中。函数hide / show正在运行。但是,只要我添加第二个联系人,它就不再起作用了。好像,jQuery没有进入显示...
function css(){
$('.contacts').css('background-color', 'lightblue');
}
function visibility() {
$("#vis").click(function(){
$(".description").toggle();
return false;
});
};
$( document ).ready(function() {
$("form").submit(function (event) {
var fname = $('#fname').val();
var lname = $('#lname').val();
var desc = $('#desc').val();
$('.contacts').append( "<div id='contact'>"+fname+"<br>"+lname+"<br><button id='vis'>Show/Hide</button><div class='description' style='display:;'>"+desc+"</div></div>");
// alert(fname);
event.preventDefault();
css();
visibility();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="#" method="get">
<fieldset>
<legend>Personal information:</legend>
First name: <input type="text" name="fname" id="fname"><br>
Last name: <input type="text" name="lname" id="lname"><br>
</fieldset>
<fieldset>
<legend>Description:</legend>
<textarea id="desc" value="desc"> </textarea><br>
<input type="submit" value="Submit">
</fieldset>
</form>
<div class="contacts"> </div>
正如我在评论中写的那样 - 你不能在html中拥有多个具有相同ID的元素。您也不必为每个按钮添加侦听器。您可以为body和selector添加侦听器作为第二个参数(请参阅附带的代码)。
function css(){
$('.contacts').css('background-color', 'lightblue');
}
$( document ).ready(function() {
//this way you don't need to add listener for each button
$('body').on('click', '.vis', function() {
$(this).closest('.contact').find('.description').toggle();
});
$("form").submit(function (event) {
var fname = $('#fname').val();
var lname = $('#lname').val();
var desc = $('#desc').val();
$('.contacts').append( "<div class='contact'>"+fname+"<br>"+lname+"<br><button class='vis'>Show/Hide</button><div class='description'>"+desc+"</div></div>");
event.preventDefault();
css();
});
});

<form action="#" method="get">
