在上面的代碼片段中,使用鉤子創建一個handsontable,一旦用戶在最右邊一列按下「right」,就會自動添加一列(使用this.alter('insert_col')
)如果用戶從那裏按下「左」,也刪除空的最右邊的列)。正如你可能看到的那樣,它的問題在於,一旦以這種方式添加了列,colHeaders就會向右移動,而不是停留在列上。這是一個錯誤還是我做錯了什麼?我該如何解決這個問題或者是否有解決方法?Handsontable:添加列移動colHeaders(如何修復?)
document.addEventListener("DOMContentLoaded", function() {
var example = document.getElementById('example1'),
hot = new Handsontable(example,{
data: Handsontable.helper.createSpreadsheetData(2, 3),
colHeaders: ["one","two","three"],
contextMenu: true
});
Handsontable.hooks.add('beforeKeyDown',function(event)
{
var $right = 39, $left = 37,
selected = this.getSelected(),
isEditMode = this.getActiveEditor().isOpened();
if(isEditMode) return;
// calc dimensions
var startColNum = selected ? (selected[1]+1) : null,
endColNum = selected ? (selected[3]+1) : null,
// endColNum is not necessarily >= startColNum, it is where selection /has ended/
rowsNum = this.countRows(),
colsNum = this.countCols(),
isFirstCol = endColNum == 0,
isLastCol = endColNum == colsNum,
i, noData, data = this.getData();
// handle arrow keys
if(isLastCol) {
if(event.which == $right)
this.alter('insert_col');
if(event.which == $left && !isFirstCol) {
noData = true;
for(i = 0; i < rowsNum; i++)
if(data[i][endColNum-1])
noData = false;
if(noData) {
this.alter('remove_col');
Handsontable.Dom.stopImmediatePropagation(event);
// don't scroll the page
if(event.preventDefault)
event.preventDefault();
}
}
}
});
});

指定插入列的索引似乎可以解決問題:this.alter('insert_col',colsNum);' – IronGeek
