HTML Table 的 insertBefore 方法中的 InvalidArgument
我想我知道这是一个 IE 错误... 我需要在 HTML 表格的确切位置添加新行。 (不想要 insertRow(index) 因为由于其他原因这看起来会更好)
function AddNewItem(td) { ///td comes from button at the HTML code, <input ... onclick="AddNewItem(this.parentNode)"
var grid = GetGrid();
var itemIndex = $(td.parentNode).attr('index');
///alert(itemIndex + "'e eklenecek");
var newRow = document.createElement('tr');
var td1 = document.createElement('td');$(td1).addClass('td');
var td2 = document.createElement('td');$(td2).addClass('td text r');
var td3 = document.createElement('td');$(td3).addClass('td text r');
var td4 = document.createElement('td');$(td4).addClass('td text r');
$(newRow).append(td1);$(newRow).append(td2);$(newRow).append(td3);$(newRow).append(td4);
grid.insertBefore(newRow, td.parentNode); ///THIS GIVES AN INVALIDARGUMENT error .. Any solutions will be appreciated :)
}
function GetGrid() {
var grid = document.getElementById("MasterTableView");
return grid;
}
I think I know this is an IE bug ...
I need to add new row to an HTML table at the exact position.
(don't want insertRow(index) cuz this looks like gonna be better for some other reasons)
function AddNewItem(td) { ///td comes from button at the HTML code, <input ... onclick="AddNewItem(this.parentNode)"
var grid = GetGrid();
var itemIndex = $(td.parentNode).attr('index');
///alert(itemIndex + "'e eklenecek");
var newRow = document.createElement('tr');
var td1 = document.createElement('td');$(td1).addClass('td');
var td2 = document.createElement('td');$(td2).addClass('td text r');
var td3 = document.createElement('td');$(td3).addClass('td text r');
var td4 = document.createElement('td');$(td4).addClass('td text r');
$(newRow).append(td1);$(newRow).append(td2);$(newRow).append(td3);$(newRow).append(td4);
grid.insertBefore(newRow, td.parentNode); ///THIS GIVES AN INVALIDARGUMENT error .. Any solutions will be appreciated :)
}
function GetGrid() {
var grid = document.getElementById("MasterTableView");
return grid;
}

我的猜测是
td.parentNode
不是grid
的子元素。看看 insertBefore 的 W3C 规范,以确保您使用有效的参数调用该方法。My guess is that
td.parentNode
is not a child element ofgrid
. Take a look at the W3C specification for insertBefore to make sure that you are calling the method with valid parameters.我猜想您向
AddNewItem
传递了一个无效参数,(至少在 IE 中)它不是像您想象的那样的td
元素。I would guess that you're passing in an invalid argument to
AddNewItem
, that (in IE, at least) it's not atd
element like you think.
