如何使用 jQuery 滚动到特定项目? [英] How to scroll to specific item using jQuery?

问题描述

我有一个带有垂直滚动条的大表格.我想使用 jQuery/JavaScript 滚动到此表中的特定行.

是否有内置方法可以做到这一点?

这里有一个小例子.

div {宽度:100px；高度:70px；边框:1px纯蓝色；溢出:自动；}

<table id="my_table"><tr id='row_1'><td>1</td></tr><tr id='row_2'><td>2</td></tr><tr id='row_3'><td>3</td></tr><tr id='row_4'><td>4</td></tr><tr id='row_5'><td>5</td></tr><tr id='row_6'><td>6</td></tr><tr id='row_7'><td>7</td></tr><tr id='row_8'><td>8</td></tr><tr id='row_9'><td>9</td></tr>

解决方案

死的简单.无需插件.

var $container = $('div'),$scrollTo = $('#row_8');$container.scrollTop($scrollTo.offset().top - $container.offset().top + $container.scrollTop());//或者您可以为滚动设置动画:$container.animate({scrollTop: $scrollTo.offset().top - $container.offset().top + $container.scrollTop()});

这是一个工作示例.

scrollTop 的文档.

I have a big table with vertical scroll bar. I would like to scroll to a specific line in this table using jQuery/JavaScript.

Are there built-in methods to do this?

Here is a little example to play with.

div {
    width: 100px;
    height: 70px;
    border: 1px solid blue;
    overflow: auto;
}

<div>
    <table id="my_table">
        <tr id='row_1'><td>1</td></tr>
        <tr id='row_2'><td>2</td></tr>
        <tr id='row_3'><td>3</td></tr>
        <tr id='row_4'><td>4</td></tr>
        <tr id='row_5'><td>5</td></tr>
        <tr id='row_6'><td>6</td></tr>
        <tr id='row_7'><td>7</td></tr>
        <tr id='row_8'><td>8</td></tr>
        <tr id='row_9'><td>9</td></tr>
    </table>
</div>

解决方案

Dead simple. No plugins needed.

var $container = $('div'),
    $scrollTo = $('#row_8');

$container.scrollTop(
    $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
);

// Or you can animate the scrolling:
$container.animate({
    scrollTop: $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
});​

Here is a working example.
