jQuery放大和缩小可滚动div，当所有内容可见时消除滚动

Question

我创建了一个包含各种列的页面。这些列可能最终离开屏幕的一侧，这是预期的默认位置。但是，我希望能够为用户提供缩小选项，以便所有列都可见。我已经关注了另一个关于如何执行此操作的堆栈溢出问题here，但它只缩放div的可见部分而不是其他内容。

＆＃13;

No rule to make target `a.c'.  Stop.

// Set initial zoom level
var zoom_level = 100;

// Click events
$('.zoom-in').click(function() {
    zoom_page(10, $(this))
});
$('.zoom-out').click(function() {
    zoom_page(-10, $(this))
});
$('.zoom-reset').click(function() {
    zoom_page(0, $(this))
});

// Zoom function
function zoom_page(step, trigger) {
    // Zoom just to steps in or out
    if (zoom_level >= 200 && step > 0 || zoom_level <= 30 && step < 0) return;

    // Set / reset zoom
    if (step == 0) zoom_level = 100;
    else zoom_level = zoom_level + step;

    var scale = zoom_level / 100;

    // Set page zoom via CSS
    $('.board-canvas').css({
        moztransform: 'scale(scale, scale)', // Moz-browsers 
        transform: 'scale(' + (scale) + ')', // set zoom
        transformOrigin: '50% 0' // set transform scale base
    });

    // Adjust page to zoom width
    if (zoom_level > 100) $('.board-canvass').css({
        width: (zoom_level * 1.2) + '%'
    });
    else $('body').css({
        width: '100%'
    });

    // Activate / deactivate trigger (use CSS to make them look different)
    if (zoom_level >= 20 || zoom_level <= 40) trigger.addClass('disabled');
    else trigger.parents('ul').find('.disabled').removeClass('disabled');
    if (zoom_level != 100) $('#zoom_reset').removeClass('disabled');
    else $('#zoom_reset').addClass('disabled');
}

如您所见，div可以缩放，但只能显示默认显示内容的级别。我希望能够缩小，以便滚动条消失。我做错了什么？

在容器流体上应用变换css

$('.container-fluid').css({
        moztransform: 'scale(scale, scale)', // Moz-browsers 
        transform: 'scale(' + (scale) + ')', // set zoom
        transformOrigin: '50% 0' // set transform scale base
});

// Set initial zoom level
var zoom_level = 100;

// Click events
$('.zoom-in').click(function() {
    zoom_page(10, $(this))
});
$('.zoom-out').click(function() {
    zoom_page(-10, $(this))
});
$('.zoom-reset').click(function() {
    zoom_page(0, $(this))
});

// Zoom function
function zoom_page(step, trigger) {
    // Zoom just to steps in or out
    if (zoom_level >= 200 && step > 0 || zoom_level <= 30 && step < 0) return;

    // Set / reset zoom
    if (step == 0) zoom_level = 100;
    else zoom_level = zoom_level + step;

    var scale = zoom_level / 100;

    // Set page zoom via CSS
        $('.container-fluid').css({
        moztransform: 'scale(scale, scale)', // Moz-browsers 
        transform: 'scale(' + (scale) + ')', // set zoom
        transformOrigin: '50% 0' // set transform scale base
        });

    // Adjust page to zoom width
    if (zoom_level > 100) $('.board-canvass').css({
        width: (zoom_level * 1.2) + '%'
    });
    else $('body').css({
        width: '100%'
    });

    // Activate / deactivate trigger (use CSS to make them look different)
    if (zoom_level >= 20 || zoom_level <= 40) trigger.addClass('disabled');
    else trigger.parents('ul').find('.disabled').removeClass('disabled');
    if (zoom_level != 100) $('#zoom_reset').removeClass('disabled');

Answer 2

如果您只是试图启用一种基本的缩放效果，从而一旦所有元素都可见后就会导致滚动行为发生变化，那么我认为您只需要将转换应用于可滚动元素内的包装器元素即可。

在下面的代码段中，我刚刚在#zoom-wrapper div内添加了一个新的#board div，并更新了zoom_page函数以转换{{1} }（我还设置了#zoom-wrapper，以便您可以看到缩放更轻松地消除了滚动-不知道您在尝试重置原点时是否还有其他想法）。

希望这能使您指向正确的方向。

transform-origin: 0 0

// Set initial zoom level
var zoom_level = 100;

// Click events
$('.zoom-in').click(function() {
    zoom_page(10, $(this))
});
$('.zoom-out').click(function() {
    zoom_page(-10, $(this))
});
$('.zoom-reset').click(function() {
    zoom_page(0, $(this))
});

// Zoom function
function zoom_page(step, trigger) {
    // Zoom just to steps in or out
    if (zoom_level >= 200 && step > 0 || zoom_level <= 30 && step < 0) return;

    // Set / reset zoom
    if (step == 0) zoom_level = 100;
    else zoom_level = zoom_level + step;

    var scale = zoom_level / 100;

    // Set page zoom via CSS
    $('#zoom-wrapper').css({
        'transform': 'scale(' + (scale) + ')', // set zoom
        'transform-origin': '0 0'
    });

    // Adjust page to zoom width
    if (zoom_level > 100) $('#zoom-wrapper').css({
        width: (zoom_level * 1.2) + '%'
    });
    else $('body').css({
        width: '100%'
    });

    // Activate / deactivate trigger (use CSS to make them look different)
    if (zoom_level >= 20 || zoom_level <= 40) trigger.addClass('disabled');
    else trigger.parents('ul').find('.disabled').removeClass('disabled');
    if (zoom_level != 100) $('#zoom_reset').removeClass('disabled');
    else $('#zoom_reset').addClass('disabled');
}

function updateLists(element, columnId) {
    //doSomething

}
