这是我的代码

$(document).ready(function () {

    // The select element to be replaced:
    var select = $('select.makeMeFancy');

    var selectBoxContainer = $('<div>', {
        width: select.outerWidth(),
        className: 'tzSelect',
        html: '<div class="selectBox"></div>'
    });

    var dropDown = $('<ul>', {className: 'dropDown'});
    var selectBox = selectBoxContainer.find('.selectBox');

    // Looping though the options of the original select element

    select.find('option').each(function (i) {
        var option = $(this);

        if (i == select.attr('selectedIndex')) {
            selectBox.html(option.text());
        }

        // As of jQuery 1.4.3 we can access HTML5 
        // data attributes with the data() method.

        if (option.data('skip')) {
            return true;
        }

        // Creating a dropdown item according to the
        // data-icon and data-html-text HTML5 attributes:

    $(document).click(function () {

    });
});


$(document).ready(function () {
    $("#drop1").click(function () {

    });
});

但有问题，

感谢

我已用此代码解决了这个问题但是有一个问题，我不知道为什么我的程序不能正常工作

BeautifulSoup

Second Problem

Answer 1

您必须将m声明为string m[5][3]而不是string m[4][2]。

您已将m声明为具有四个行和两个列的静态字符串数组。因此，行数为{0,1,2,3}，列数为{0,1}。

但是，在您的外圈i中，从0更改为4（例如i = {0,1,2,3， 4 }）。在最后一次迭代时达到索引4，并且它超出了数组m的行的范围。因此，当您尝试读取最后一行时，程序将失败。

此外，阵列m中只有两列。因此，当j索引从0变为3时，您对内存的写入也不正确。
