我正在尝试在地址簿的按钮元素上使用单击功能。我想在点击按钮时输入用户输入的联系人姓名然后编号,但我收到了
"意外的标识符"错误。
我的联系人存储在表格中的html文档中;这是我的代码:
$(document).ready(function() {
$('#add').click(function() {
var toAddName = $('input[name=contact]').val();
var toAddNum = $('input[name=number]').val();
$('#contacts').append('<tr><th>'+toAddName+'</th><td>'+toAddNum+'</td></tr>');
});
});
我也试过这个:
var name = prompt("Name: ");
var number = prompt("Number: ");
$(document).ready(function() {
$('#add').click(function() {
$('table').append('<tr><th>'name'</th><td>'number'</td></tr>');
});
});
以下是我的所有JS / CSS / HTML代码:
(P.S。我知道我的javascript和我的CSS都链接到html,但我使用的代码编辑器为我做了这个)
var name = prompt("Name: ");
var number = prompt("Number: ");
$(document).ready(function() {
$('#add').click(function() {
$('table').append('<tr><th>'name'</th><td>'number'</td></tr>');
});
});

您需要连接name
和number
。另外,在下面的代码中,我在name
number
和New Contact
$(document).ready(function() {
$('#add button').click(function() { // bind to button
var name = prompt("Name: ");
var number = prompt("Number: ");
$('table').append('<tr><th>' + name + '</th><td>' + number + '</td></tr>');
});
});
&#13;
table {
font-size: 20px;
margin-left: 10px;
margin-top: 15px;
}
th {
padding-right: 100px;
}
#add {
display: inline-block;
padding-left: 10px;
padding-right: 10px;
font-size: 14px;
margin-right: 50px;
color: blue;
}
#del {
display: inline-block;
padding-left: 10px;
padding-right: 10px;
font-size: 14px;
color: red;
}

使用+(concatenation operator)
运算符连接变量并在点击处理函数中调用prompt
,以便每次&#34; New Contact&#34; 时都会要求输入点击。
concatenation operator
(+)
将两个字符串值连接在一起,返回另一个字符串,即两个操作数字符串的union
。
$('#add').click(function() {
var name = prompt("Name: ");
var number = prompt("Number: ");
$('table').append('<tr><th>' + name + '</th><td>' + number + '</td></tr>');
});
$('#add').click(function() {
var name = prompt("Name: ");
var number = prompt("Number: ");
$('table').append('<tr><th>' + name + '</th><td>' + number + '</td></tr>');
});

这一行
$('table').append('<tr><th>'name'</th><td>'number'</td></tr>');
应改为:
$('table').append('<tr><th>' + name+ '</th><td>' + number + '</td></tr>');

试试这个,你需要做的只是使用连接:D
$(document).ready(function() {
$('#add').click(function() {
var name = prompt("Name: ");
var number = prompt("Number: ");
$('table').append('<tr><th>'+name+'</th><td>'+number+'</td></tr>');
});
});
