JQuery - 相对于按钮的位置弹出 [英] JQuery - Position Popup in relative to button(s)

问题描述

我试图相对于其按钮或用jquery点击的按钮定位一个弹出窗口。我想把弹出窗口放在一个不覆盖按钮本身的方式。将其放置在所单击的按钮的左侧，右侧，上方或下方。

I'm trying to position a popup relative to its button or the button that is clicked with jquery. I'd like to position the popup in a way that doesn't cover up the button itself. Position it to the left, right, above or below the button that is clicked.

现在我知道我可以通过编写更多的html弹出框和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。我试着使用偏移和位置（在一个点），但我不能得到它的工作。坦率地说，我很高级的js和jquery所以原谅我的noobness。

Now I know I can do this by writing more html popups and css but there got to be a way to dynamically use one div and position it with jquery. I tried using offsets and position (at one point) but I couldn't get it to work. Frankly, I'm very entry level with js and jquery so forgive my noobness.

任何帮助将非常感谢！

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');

 });

推荐答案

创建一个单独的函数来显示问题，问题作为参数：

Create a separate function to display the question, which takes the clicked button and the question as parameters:

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()
    });
}

这样调用：

$('.trends').click(function () {
  showQuestion(
    $(this), 
    '<p>What trends could potentially drive growth in the U.S.?</p>'
  );
});

Updated Fiddle

css 将始终显示在屏幕上。

The css left calculation ensures that the question will always be on-screen.
