使用 contenteditable 在生成的 table 中触发 onkeyup
Fire onkeyup in generated table with contenteditable
我的 javascript 中有一个小问题,我已经坚持了一段时间了。
我所做的是:
- 创建一个空 table。
在 table(来自 JSON-object)中生成 tr/td 标签和值。
for (var i = 0 ; i < myList.length ; i++) {
var row$ = $('<tr/>');
for (var colIndex = 0 ; colIndex < columns.length ; colIndex++) {
var cellValue = myList[i][columns[colIndex]];
if(colIndex == columns.indexOf("type"))
{
var box$ = $('<td/>');
if(cellValue == "Organisation")
box$.addClass( "uk-badge uk-badge-danger" );
else
box$.addClass( "uk-badge uk-badge-primary" );
box$.html(cellValue);
row$.append(box$);
}
else
{
var box$ = $('<td/>');
box$.html(cellValue);
box$.attr('contenteditable','true');
box$.attr('onkeyup','updateJSON('+colIndex+','+i+')');
row$.append(box$);
}
}
$(selector).append(row$);
}
- table 看起来不错:
td contenteditable="true" onkeyup="updateJSON(3,0)">Timmy/td>
生成 table 并且我编辑字段时出现问题。 'onkeyup' 不应该 'fire'。将 'onkeyup' 替换为 'onclick' 就可以了。我不知道为什么这不起作用,有人可以帮忙吗?

应该为您的 <td>
元素设置,而不是 <table>
.
否则td
不会触发事件
所以在你的循环中添加 box$.attr('contenteditable','true');
。
