通过JavaScript / jQuery单击按钮来调用单击函数

Question

Here's my JavaScript:

function privacy(current)
{
    var $this = $(current), 
    $scope = $this.closest('.uk-button-group'), 
    value = $this.val();
    $.ajax({
        type: 'post',
        url: '/privacy.php',
        data: {key: value },
        success: function () {
        }
    });
}
$(function() {
    $("#privacy1, #privacy2, #privacy3").click(function() {
        privacy($this);
        alert('A button has been clicked!');
    });
});

And here's my HTML:

<div class="uk-button-group">
    <button class="uk-button" id="privacy1" value="1">Public</button>
    <button class="uk-button" id="privacy2" value="2">Protected</button>
    <button class="uk-button" id="privacy3" value="3">Private</button>
</div>    

When I click on one of the buttons, it should call the privacy function and alert me that a button has been clicked but it doesn't. Can anyone help me and show me what's wrong with my code? Much appreciated thank you!

Answer 1

You do not have any identifier $this , you probably need to change $this with $(this) or simply this to pass the event source object

privacy(this);

OR

privacy($(this));

Answer 2

替换为：

privacy(this);

Answer 3

Try here: http://jsfiddle.net/pqdgT/

$(function() {
    $("#privacy1, #privacy2, #privacy3").click(function() {
        privacy($(this));
        alert('A button has been clicked!');
    });
});

Answer 4

Here is your working code

And here is the refined code

function privacy(current)
{
    var btn = $(current), 
    scope = $(btn).closest('.uk-button-group'), 
    value = $(btn).val();
    $.ajax({
        type: 'post',
        url: '/privacy.php',
        data: {key: value },
        success: function () {
        }
    });
}
$(function() {
    $("#privacy1, #privacy2, #privacy3").click(function() {
        privacy(this);
        alert('A button has been clicked!');
    });
});
