我有一张包含某些TR的表格。 我想要的是，当我点击任何tr然后打开一个弹出窗口。但是我无法操纵它的位置到上面点击它的上面。
var modal = document.getElementById('myModal');
// Get the button that opens the modal
var btn = document.getElementById("tr_1");
// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close_div")[0];
// When the user clicks the button, open the modal
btn.onclick = function() {
modal.style.display = "block";
}
// When the user clicks on <span> (x), close the modal
span.onclick = function() {
modal.style.display = "none";
}
// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
if (event.target == modal) {
modal.style.display = "none";
}

当我点击tr中的任何一个时，弹出框应位于相应的tr上方，并使用底部三角形指向tr。
我搜索了很多，但它对我不起作用。 任何帮助都会很棒。 谢谢。
答案 0 :(得分：1)
使用bootstrap popover而不是模态。连同链接中的解释内容，在tr的click函数中，将放置参数传递给popover方法，如下所示：
$('tr').popover({
content: //Your Html with textbox and button
, container: 'body'
, placement: 'auto top'
, html: true
});
$(selector).popover('show');
更新：下面给出了完整的工作html，删除了整个bootstrap模式html并将展示位置更改为自动顶部。如果上面没有空格，则使用“自动”，弹出窗口将显示在下方。
