我正在尝试相对于其按钮或使用jquery单击的按钮定位弹出窗口。我想以一种不掩盖按钮本身的方式定位弹出窗口。将其放置在单击按钮的左侧,右侧,上方或下方。
现在我知道我可以通过编写更多的html弹出窗口和css来做到这一点但是必须有一种方法来动态使用一个div并用jquery定位它。我尝试使用偏移和位置(在某一点上),但我无法让它工作。坦率地说,我是js和jquery的入门级别,请原谅我的高唱。
非常感谢任何帮助!!
JS:
$('.trends').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>What trends could potentially drive growth in the U.S.?</p>');
/* if I add this and zero out the positioning via css the pop gets offset but its way far away from this parent.
var offset = $(this).offset();
$('.questions').css('left',offset.left);
$('.questions').css('top',offset.top);*/
});
$('.consumer').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>Even though we have low inflation, consumers are not increasing their spending. Why?</p>');
});
$('.industry').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>What factors drove crude oil prices to fall and which industries benefited?</p>');
});
$('.henn').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>MESSAGE FROM OUR PRESIDENT</p>');
var offset = $(this).offset();
$('.question').html('<p>What trends could potentially drive growth in the U.S.?</p>');
});
$('.equity').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>The U.S. stock market has been rising for more than six years. What do you see ahead for equities?</p>');
});
$('.balance').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>what does it look like for companies balance sheets?</p>');
});
$('.close').click(function (e) {
e.stopPropagation();
$(this).parent().hide();
$('.items').removeClass('no-effect');
});

创建一个单独的函数来显示问题,该问题将单击的按钮和问题作为参数:
function showQuestion(button, question) {
var offset = button.offset();
$('.question').html(question);
$('.questions')
.fadeIn()
.css({
left: Math.min(offset.left, $(window).innerWidth()-$('.questions').outerWidth()),
top: offset.top + button.innerHeight()
});
}
这样称呼:
$('.trends').click(function () {
showQuestion(
$(this),
'<p>What trends could potentially drive growth in the U.S.?</p>'
);
});
css
左计算可确保问题始终显示在屏幕上。

您的部分问题是.filter
设置为position: relative;
。
如果绝对定位元素具有相对定位的父元素,则绝对元素将相对于父元素而不是文档定位。
如果你删除它会更容易使用.offset()
来定位问题:
<强> Working Example 强>
$('.trends').click(function () {
$('.questions').fadeIn();
$('.question').html('<p>What trends could potentially drive growth in the U.S.?</p>');
/* See change here*/
var offset = $(this).offset();
$('.questions').css('top', offset.top + $(this).height());
});
.filter {
width: 98.1481481481%;
float: left;
margin-left: 0.9259259259%;
margin-right: 0.9259259259%;
margin-bottom: 10px;
/*position: relative; see change here */
}

jQuery中有一个$(...)。position()函数可以帮助你。我重构了你的代码以避免重复行,但它的要点是:
function popup(jqBtn, question){
// mind that the .position does not account for borders etc.
var btn = $(jqBtn).parents('.buttons'),
posLeft = btn.position().left + btn.outerWidth(),
posTop = btn.position().top;
$('.questions').fadeIn();
$('.question').html(question);
$('.questions')
.appendTo(btn.parent())
.css('left', posLeft + 'px')
.css('top', posTop + 'px');
}
// a sample of binding a button to the popup() function
$('.trends').click(function () {
popup(this, '<p>What trends could potentially drive growth in the U.S.?</p>');
});
因此该函数重新附加'questions'div以使其具有与按钮相同的父级。该按钮基于单击的元素找到,遍历结构以查找“.buttons”类的元素。如果结构变得更复杂,可能需要进行调整。
