当用户点击时,我设法'突出显示'一个单元格(td-element) 然而,我希望整个专栏都是高亮的,而电池本身则略有不同 我无法完成最后一部分(突出显示整个专栏)。 感谢所有的帮助。
期望的结果如下所示:
function handleBlur(event) {
event.target.contentEditable = false;
}
document.querySelector('body').addEventListener('click', function(event) {
if (event.target.tagName.toLowerCase() === 'td') {
event.target.contentEditable = true;
event.target.focus();
event.target.addEventListener("blur", handleBlur);
}
});
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 500px;
margin: 50px 0 0 50px;
}
td,
th {
border: 1px solid #dddddd;
text-align: left;
padding: 8px;
}
th {
background-color: white;
}
table td[contentEditable=true]{
-webkit-box-shadow: inset 0px 0px 0px 200px rgba(186,210,225,0.51);
-moz-box-shadow: inset 0px 0px 0px 200px rgba(186,210,225,0.51);
box-shadow: inset 0px 0px 0px 200px rgba(186,210,225,0.51);
outline: 3px solid #086AA7;}

现在,通过使用本机DOM apis,您可以在不使用jQuery的情况下轻松完成此任务。
在其父级的子级(使用cellIndex
)中查找所选单元格的索引,然后迭代cols,并更改{col
中的相关colgroup
的背景1}}:
function handleBlur(event) {
event.target.contentEditable = false;
}
var cols = document.querySelectorAll('col'); // find the cols and cache
document.querySelector('body').addEventListener('click', function(event) {
var t = event.target;
if (t.tagName.toLowerCase() !== 'td') {
return;
}
t.contentEditable = true;
t.focus();
t.addEventListener("blur", handleBlur);
var highlightIndex = t.cellIndex; // the index of the clicked item in the row
cols.forEach(function(col, index) { // iterate the cols
col.style.background = index === highlightIndex ? 'lightblue' : null; // set the background to the clicked col, remove from others
});
});
