在Javascript数据表中自动换行列数据 [英] Word wrap column data in Javascript datatable
问题描述
我有一个JS数据表,我们在其中输入客户信息,在某些情况下,某些客户参考是这样的
I have a JS datatable where we input customer information, on certain case some customer reference are as such
reference_text=%26reference%5Ftext%3D%2526reference%255Ftext%253Dtest%252520ipsum%25252C%25252008%25252DAug%25252D08%2546%26&
这会破坏我的html表,并迫使一列不成比例地增长,因为它不包含空格,我在JS小提琴中设置了一个示例来说明此问题,有没有一种方法可以强制将该列放入是否与其他格式保持一致,还是将文本换行以使其适合该列?
This breaks my html table and forces a column to grow out of proportion as this does not contain a space, i have setup a example in JS fiddle to illustrate this issue, is there a way we can force this column to be in a consistent format with the other or wrap the text to make it fit in the column?
$(document).ready(function () {
if ($('#report_gen_user').length) {
$('#report_gen_user').dataTable(
{
"iDisplayLength": -1,
initComplete: function () {
var api = this.api();
api.columns().indexes().flatten().each(function (i) {
if (i == 2 || i == 9) {
var column = api.column(i);
var select = $('<select><option value=""></option></select>')
.appendTo($(column.footer()).empty())
.on('change', function () {
var val = $.fn.dataTable.util.escapeRegex(
$(this).val()
);
column
.search(val ? '^' + val + '$' : '', true, false)
.draw();
});
column.data().unique().sort().each(function (d, j) {
select.append('<option value="' + d + '">' + d + '</option>')
});
$(".hidefooter").html("");
}
});
},
"aLengthMenu": [
[15, 25, 35, 50, 100, -1],
[15, 25, 35, 50, 100, "All"]
],
"aoColumnDefs": [{
"bVisible": false,
"aTargets": []
}],
"aaSorting": [],
"fnFooterCallback": function (nRow, aasData, iStart, iEnd, aiDisplay) {
var columnas = [1, 5]; //the columns you wish to add
for (var j in columnas) {
var columnaActual = columnas[j];
var total = 0;
var allTimeTotal = 0;
for (var i = iStart; i < iEnd; i++) {
total = total + parseFloat(aasData[aiDisplay[i]][columnaActual]);
}
total = total.toFixed(2);
for (var counter in aasData) {
allTimeTotal = allTimeTotal + parseFloat(aasData[counter][columnaActual]);
//console.log((aasData[counter][columnaActual]));
}
allTimeTotal = allTimeTotal.toFixed(2);
if (total == allTimeTotal) {
$($(nRow).children().get(columnaActual)).html(' '+total);
} else {
$($(nRow).children().get(columnaActual)).html(' '+total + ' (' + allTimeTotal + ')');
}
} // end
}
}
);
}
})

推荐答案
将autoWidth
设置为false并定义您喜欢的column
width
:
Set autoWidth
to false and define your prefered column
width
's :
var table = $('#example').DataTable({
autoWidth: false,
columns : [
{ width : '50px' },
{ width : '50px' },
{ width : '50px' },
{ width : '50px' },
{ width : '50px' },
{ width : '50px' }
]
});
然后,最重要-添加此CSS:
then, most important - add this CSS :
table.dataTable tbody td {
word-break: break-word;
vertical-align: top;
}
word-break
是重要的部分,vertical-top
是眼睛的:)
word-break
is the important part, vertical-top
is for the eyes :)

在您的小提琴中,上面的内容似乎不起作用,但这是因为您将每个字符串作为值添加到<select>
中,结果最终变得更长.为了防止这种情况,请在插入长字符串作为<option>
值之前先将其剪掉.您可以在末尾添加...
:
In your fiddle the above seems not to work, but that is because you add each and every string as values to a <select>
that ends up being even longer. To prevent that, cut long strings off before inserting them as <option>
values; you can add ...
to the end :
column.data().unique().sort().each(function (d, j) {
if (d.length>25) { d=d.substring(0,25)+'...' }
select.append('<option value="' + d + '">' + d + '</option>')
});
