带有jQuery分页的HTML表

Question

I am trying to create a table such that when there are more than 10 rows I want to create a hyperlink which tells the user to go on the next page. 我正在尝试创建一个表，当有超过10行时，我想创建一个超链接，告诉用户进入下一页。 The concept is called pagination, but how can I achieve it with jQuery / JavaScript ? 这个概念叫做分页，但我怎样才能用jQuery / JavaScript实现呢？

Alternatively to the plugin, if you want to see simplified code so you can educate yourself as to how pagination works, have a look at this fiddle I knocked up for you. 作为插件的替代方案，如果你想看到简化的代码，这样你就可以自己了解分页的工作方式，看看这个小提琴，我为你敲了一下。

http://jsfiddle.net/29W9Q/ http://jsfiddle.net/29W9Q/

The code simply binds two buttons, previous and next to change the visibility of the rows of the table that you specified. 代码只是绑定两个按钮，上一个和下一个按钮，以更改您指定的表的行的可见性。 Each time a button is clicked, the steps are: see if you can move backward or forward, hide the current rows, find the rows that should be visible, 10 up or 10 down, and then make them visible. 每次单击按钮时，步骤为：查看是否可以向后或向前移动，隐藏当前行，查找应该可见的行，向上或向下10行，然后使它们可见。 The rest of the code is to illustrate the example. 其余代码用于说明示例。

The real jQuery work is being done by the less-than and greater-than selectors: :lt() and :gt() , to select the rows for hiding/showing. 真正的jQuery工作由小于和大于选择器完成:lt()和:gt() ，以选择隐藏/显示的行。

var maxRows = 10;
$('.paginated-table').each(function() {
    var cTable = $(this);
    var cRows = cTable.find('tr:gt(0)');
    var cRowCount = cRows.size();

    if (cRowCount < maxRows) {
        return;
    }

    /* add numbers to the rows for visuals on the demo */
    cRows.each(function(i) {
        $(this).find('td:first').text(function(j, val) {
           return (i + 1) + " - " + val;
        }); 
    });

    /* hide all rows above the max initially */
    cRows.filter(':gt(' + (maxRows - 1) + ')').hide();

    var cPrev = cTable.siblings('.prev');
    var cNext = cTable.siblings('.next');

    /* start with previous disabled */
    cPrev.addClass('disabled');

    cPrev.click(function() {
        var cFirstVisible = cRows.index(cRows.filter(':visible'));

        if (cPrev.hasClass('disabled')) {
            return false;
        }

        cRows.hide();
        if (cFirstVisible - maxRows - 1 > 0) {
            cRows.filter(':lt(' + cFirstVisible + '):gt(' + (cFirstVisible - maxRows - 1) + ')').show();
        } else {
            cRows.filter(':lt(' + cFirstVisible + ')').show();
        }

        if (cFirstVisible - maxRows <= 0) {
            cPrev.addClass('disabled');
        }

        cNext.removeClass('disabled');

        return false;
    });

    cNext.click(function() {
        var cFirstVisible = cRows.index(cRows.filter(':visible'));

        if (cNext.hasClass('disabled')) {
            return false;
        }

        cRows.hide();
        cRows.filter(':lt(' + (cFirstVisible +2 * maxRows) + '):gt(' + (cFirstVisible + maxRows - 1) + ')').show();

        if (cFirstVisible + 2 * maxRows >= cRows.size()) {
            cNext.addClass('disabled');
        }

        cPrev.removeClass('disabled');

        return false;
    });

});
