如何在点击时触发事件？

时间：2018-04-11 07:45:55

标签： jquery onclick click

我期待通过点击“项目”，点击“点击”警报。但没有任何反应

jQuery(document).ready(function() {
  jQuery(".main-table").clone(true).appendTo('#table-scroll').addClass('clone');
});


$('.table-wrap').scrollLeft($('[data-date="2018-04-01"]').offset().left - 82);



$( ".project" ).on( "click", function() {
  alert("clicked");
});
.table-scroll {
  position: relative;
  margin: auto;
  overflow: hidden;
}

.table-wrap {
  width: 100%;
  overflow: auto;
}

.table-scroll table {
  width: 100%;
  margin: auto;
  border-collapse: separate;
  border-spacing: 0;
}

.table-scroll th,
.table-scroll td {
  padding: 5px 10px;
  white-space: nowrap;
  vertical-align: top;
}

.clone {
  position: absolute;
  top: 0;
  left: 0;
  pointer-events: none;
}

.clone th,
.clone td {
  visibility: hidden
}

.clone td,
.clone th {
  border-color: transparent
}

.clone tbody th {
  visibility: visible;
}

.clone .fixed-side {
  visibility: visible;
  background-color: #fff;
  font-weight: normal;
  border: none;
  border-right: 2px solid #f4f4f4;
}

.clone thead,
.clone tfoot {
  background: transparent;
}

.gantt-h {
  font-weight: normal;
  color: #b0b0b0;
  border-right: 2px solid #f4f4f4;
}

.last {
  border-right: 2px solid #f4f4f4;
}

.gantt td {
  border-right: 2px solid #f4f4f4;
}

.today{
background-color:pink;
width:100px;
cursor:pointer
}

这只是一种解决方法。主要思想是计算您点击的坐标并检查是否在th的范围内。

注意：您可以根据此代码找到您点击的th。

修改：现在仅在点击th

中的第一个tbody时触发 

jQuery(document).ready(function() {
  jQuery(".main-table").clone(true).appendTo('#table-scroll').addClass('clone');
});


$('.table-wrap').scrollLeft($('[data-date="2018-04-01"]').offset().left - 82);



// $( ".project" ).on( "click", function() {
//   alert("clicked");
// });

$("body").on("click", function(e) {
  // the coordinate you clicked
  var x = e.clientX
  var y = e.clientY
  
  // all th.fixed-side in cloned table (include thead and tbody)
  var fixedSide = $('table.clone th.fixed-side')

  // calculate the height of cloned table's tbody
  // var tableHeight = fixedSide.get(0).offsetHeight * fixedSide.length - 1;

  // only first th in tbody
  var tableHeight = fixedSide.get(0).offsetHeight;

  // th's width
  var offsetWidth = fixedSide.get(0).offsetWidth;

  // calculate offsetTop and offsetLeft from body
  var offset = getOffset(fixedSide.get(0))
  
  // skip thead's th
  offset.Top += fixedSide.get(0).offsetHeight;

  // check if click inside the range
  var inRange = (x >= offset.Left && x <= offset.Left + offsetWidth) &&
    (y >= offset.Top && y <= offset.Top + tableHeight)

  if (inRange) {
    alert("clicked");
  }
});

function getOffset(element) {
  var offsetTop = 0;
  var offsetLeft = 0;
  do {
    offsetTop += element.offsetTop;
    offsetLeft += element.offsetLeft;
  } while (element = element.offsetParent);
  var offset = {
    Left: offsetLeft,
    Top: offsetTop,
  }
  return offset;
}

问题在于你的CSS。您不需要使用table-wrap类。删除该CSS，它将起作用：

＆＃13;
＆＃13; 
jQuery(document).ready(function() {
  jQuery(".main-table").clone(true).appendTo('#table-scroll').addClass('clone');
});


$('.table-wrap').scrollLeft($('[data-date="2018-04-01"]').offset().left - 82);



$( ".project" ).on( "click", function() {
  alert("clicked");
});
＆＃13; 
.table-scroll {
  position: relative;
  margin: auto;
  overflow: hidden;
}

.table-scroll table {
  width: 100%;
  margin: auto;
  border-collapse: separate;
  border-spacing: 0;
}

.table-scroll th,
.table-scroll td {
  padding: 5px 10px;
  white-space: nowrap;
  vertical-align: top;
}

.clone {
  position: absolute;
  top: 0;
  left: 0;
  pointer-events: none;
}

.clone th,
.clone td {
  visibility: hidden
}

.clone td,
.clone th {
  border-color: transparent
}

.clone tbody th {
  visibility: visible;
}

.clone .fixed-side {
  visibility: visible;
  background-color: #fff;
  font-weight: normal;
  border: none;
  border-right: 2px solid #f4f4f4;
}

.clone thead,
.clone tfoot {
  background: transparent;
}

.gantt-h {
  font-weight: normal;
  color: #b0b0b0;
  border-right: 2px solid #f4f4f4;
}

.last {
  border-right: 2px solid #f4f4f4;
}

.gantt td {

.today{
