我在MVC环境中使用Facebook评论插件,当我添加评论时,控制台崩溃并显示500错误。页面加载期间加载所有注释时,我不出现错误。但是,注释已成功添加到URL ,因此在创建创建内容后发生错误。
这里的相关代码,已尽可能地清理(底部的JavaScript)
buttons: [
{
extend: 'excel',
customize: function (xlsx) {
//Apply styles, Center alignment of text and making it bold.
var sSh = xlsx.xl['styles.xml'];
var lastXfIndex = $('cellXfs xf', sSh).length - 1;
var n1 = '<numFmt formatCode="##0.0000%" numFmtId="300"/>';
var s2 = '<xf numFmtId="0" fontId="2" fillId="0" borderId="0" applyFont="1" applyFill="0" applyBorder="0" xfId="0" applyAlignment="1">' +
'<alignment horizontal="center"/></xf>';
'<alignment horizontal="center"/></xf>';
sSh.childNodes[0].childNodes[0].innerHTML += n1;
sSh.childNodes[0].childNodes[5].innerHTML += s2;
var greyBoldCentered = lastXfIndex + 1;
//Merge cells as per the table's colspan
var sheet = xlsx.xl.worksheets['sheet1.xml'];
var dt = $('#tblReport').DataTable();
var frColSpan = $(dt.table().header()).find('th:nth-child(1)').prop('colspan');
var srColSpan = $(dt.table().header()).find('th:nth-child(2)').prop('colspan');
var columnToStart = 2;
var mergeCells = $('mergeCells', sheet);
mergeCells[0].appendChild(_createNode(sheet, 'mergeCell', {
attr: {
ref: 'A1:' + toColumnName(frColSpan) + '1'
}
}));
mergeCells.attr('count', mergeCells.attr('count') + 1);
var columnToStart = 2;
while (columnToStart <= frColSpan) {
mergeCells[0].appendChild(_createNode(sheet, 'mergeCell', {
attr: {
ref: toColumnName(columnToStart) + '2:' + toColumnName((columnToStart - 1) + srColSpan) + '2'
}
}));
columnToStart = columnToStart + srColSpan;
mergeCells.attr('count', mergeCells.attr('count') + 1);
}
//Text alignment to center and apply bold
$('row:nth-child(1) c:nth-child(1)', sheet).attr('s', greyBoldCentered);
for (i = 0; i < frColSpan; i++) {
$('row:nth-child(2) c:nth-child(' + i + ')', sheet).attr('s', greyBoldCentered);
}
function _createNode(doc, nodeName, opts) {
var tempNode = doc.createElement(nodeName);
if (opts) {
if (opts.attr) {
$(tempNode).attr(opts.attr);
}
if (opts.children) {
$.each(opts.children, function (key, value) {
tempNode.appendChild(value);
});
}
if (opts.text !== null && opts.text !== undefined) {
tempNode.appendChild(doc.createTextNode(opts.text));
}
}
return tempNode;
}
//Function to fetch the cell name
function toColumnName(num) {
for (var ret = '', a = 1, b = 26; (num -= a) >= 0; a = b, b *= 26) {
ret = String.fromCharCode(parseInt((num % b) / a) + 65) + ret;
}
return ret;
}
}
}
]
我不知道该如何调试。
错误看起来像这样(同样,添加注释后也这样):
答案 0 :(得分:1)
答案很简单!该代码无效!
<div class="fb-comments" style="display: none;" data-href="http://localhost:36998/blog#@post.Slug" data-numposts="5"></div>
data-href
属性
不能是localhost。我将其更改为其他内容,并且有效!
