我正在检查表格中的重复项。我想要完成的是当我显示第一列时,如果它与前一行的值相同,我不想显示该值。我找到了重复项,但是当我尝试使用显示隐藏它们时出现错误。 style =“none”;我的代码如下。
我提前感谢你 PD
var data=[['e',0,1,2,3,4], ['a',54312,235,5,15,4], ['a',6,7,8,9,232],
['a',54,11235,345,5,6], ['b',0,1,2,3,4], ['b',54312,235,5,15,4],
['c',62,15,754,93,323], ['d',27,11235,425,18,78], ['d',0,1,2,3,4],
['d',54312,235,5,15,4], ['e',6,7,8,9,232], ['e',54,11235,345,5,6],
['e',0,1,2,3,4], ['e',54312,235,5,15,4], ['e',62,15,754,93,323],
['e',27,11235,425,18,78]];
//Create a HTML Table element.
var table = document.createElement("TABLE");
var somedata = document.createElement("TD");
var dvTable = document.getElementById("dvTable");
var elems = document.getElementsByClassName("tableRow");
//Get the count of columns.
var columnCount = data[0].length;
//Add the data rows.
for (var i = 0; i < data.length; i++) {
var row = table.insertRow(-1);
for (var j = 0; j < columnCount; j++) {
//Searching for duplicates
var num = data[i][0];
for (var otherRow = i + 1; otherRow < data.length; otherRow++) {
var dup = data[otherRow][0];
console.log("What is the dup" + dup);
if (num === dup)
{
console.log("duplicate");
dvTable[i].style.display = "none";
}
}
var cell = row.insertCell(-1);
cell.innerHTML = data[i][j];
cell.innerHtml = myZero;
}
}
答案 0 :(得分:0)
dvTable
是一个HTML表格元素。您无法使用dvTable[i]
访问该行。
尝试 -
dvTable.rows(i).cells(j).style.display = none;
