Question

我们正在容器中显示文本，如下所示：

Onclick文本，我们正在做以下事情：

1。允许用户添加更多文本

2。显示弹出框

问题：

当用户添加更多文本时，它显示在容器之外，但是我们想隐藏显示在容器之外的文本。...

因此我们为容器添加了overflow: hidden;，但现在仅显示 partial 弹出框，如下所示。...

//  Close text pop up onclick outside

$(document).mouseup(function(e) {
    var container = $('.white_content, .font-select');

    // if the target of the click isn't the container nor a descendant of the container
    if (!container.is(e.target) && container.has(e.target).length === 0) {
        container.hide();
        $('.font-select').css('display', 'none');
    }
});

// end

var className;

// Display pop up next to text

function closePopUp(el) {
    el.style.display = 'none';
    $('.font-select').css('display', 'none');
    openID = null
}

function openPopUp(el) {
    // console.log(el);
    if (openID != null) {
        closePopUp(openID)
    }

    $('.font-select:first').css({

Answer 1

您必须在max-width中应用.txtContainer，然后从容器类中删除position: relative;。

通过删除position属性，div将排在最前面，通过添加max-width，锚标记将不会增加。

只需更新CSS类以上

：

.txtContainer {
    position: absolute;
    color: #FFF;
    white-space: pre;
    max-width: 50px;
}

.container {
    background: silver;
    /* position: relative; */
    overflow: hidden;
}

使用拖动功能更新答案：

    // if the target of the click isn't the container nor a descendant of the container
    if (!container.is(e.target) && container.has(e.target).length === 0) {
        container.hide();
        $('.font-select').css('display', 'none');
    }
});

// end

var className;

// Display pop up next to text

function closePopUp(el) {
    el.style.display = 'none';
    $('.font-select').css('display', 'none');
