Question

I m 试图将1(一)从价值中分离出来。我设法这样做:

$( .notis ).text(parseInt($(".notis").text()) - 1);

问题在于:<代码><a> 。

<a href="#" class="notis"><img src="/images/icons/picture.png">3</a>

因此,上面的分类将从价值中减去1(一个),但也消除形象! 我怎么能够这样做?

Answer 1

You can store the image in a temporary variable, then add it to the node using the prepend method:

$( .notis ).each(function() {
    var $this = $(this);                        // <-- Reference to current elem
    var $img = $this.find( img );               // <-- Reference to <img>
    $this.text(parseInt($this.text(), 10) - 1); // <-- Your logic
    $this.prepend($img);                        // <-- Add image again.
});

附加说明:

Use parseInt( ... , 10) instead of parseInt( ... ). Numbers prefixed by a zero will be treated inconsistently across browsers. By specifygin the radix of 10, the number will be parsed correctly.
$( .notis ) selects all elements with class notis. When you re using $( notis ).text($( notis ).text()-1), all elements with class notis will contain the value of the first .notis element (because $( .notis ).text() returns the value of the first .notis). That s why I used .each in my code.
When you re going to use $(this) more than once, it s worth storing the variable $(this) in a temporary variable, for improved efficiency.

也许可以找到更好的解决办法,但是,在你修改案文之后,你可以挽救儿童联系内容,重新引导他们:

$( .notis ).each(function (index, element) {
    var $children = $(this).children();
    $(this).text(parseInt($(this).text()) - 1).prepend($children);
});

I d suggest to wrap up the number in a <span> and replace its content.

最好的解决办法是围绕您的号码安装span。这导致业绩最佳。
