我有一个带有复选框和按钮验证的数据表(矩阵,薪水,工作日数和保险费),我想在单击按钮验证时计算总和值,但是有一个错误,该值不等于NaN。 / p>
<table class="table table-bordered" id="mytable">
<tr>
<th><input type="checkbox" id="check_all"></th>
<th>matricule</th>
<th>salary</th>
<th>number day</th>
<th>premium</th>
</tr>
<tr>
<td><input type="checkbox" class="checkbox"></td>
<td>1</td>
<td>5000</td>
<td>2</td>
<td><input type="text" name="prime" class="form-control" value="0"></td>
</tr>
<tr>
<td><input type="checkbox" class="checkbox"></td>
<td>2</td>
<td>6000</td>
<td>2</td>
<td><input type="text" name="prime" class="form-control" value="0"></td>
</tr>
<tr>
<td><input type="checkbox" class="checkbox"></td>
<td>1</td>
<td>7000</td>
<td>1</td>
<td><input type="text" name="prime" class="form-control" value="0"></td>
</tr>
</table>
<div class="form-group col-md-offset-5 ">
<button class="btn btn-success add-all" type="submit" id="hide">Pointage men</button>
</div>
用于全部检查并获取一些值并计算总和的jQuery代码:
$(document).ready(function() {
$('#check_all').on('click', function(e) {
if ($(this).is(':checked', true)) {
$(".checkbox").prop('checked', true);
} else {
$(".checkbox").prop('checked', false);
}
});
$('.checkbox').on('click', function() {
if ($('.checkbox:checked').length == $('.checkbox').length) {
$('#check_all').prop('checked', true);
} else {
$('#check_all').prop('checked', false);
}
});
// jquery code for display array :
$("#hide").click(function() {
var items = [];
$("tr").each(function(i, r) {
if (i > 0 && $(r).find("input").first().prop("checked")) {
//sum = (((salary/24)*nbre)+premium)
let sum = ((($(r.cells[2]).innerText / 24) * $(r.cells[3]).innerText) + $(r.cells[4]).find('input').val());
items.push({
"matricule": r.cells[1].innerText,
"salary": r.cells[2].innerText,
"nbre": r.cells[3].innerText,
"premium": $(r.cells[4]).find('input').val(),
"sum": sum
})
}
});
console.log(items);
});
})

将innerText
替换为text()
,然后使用parseInt
进行计算。
$(document).ready(function() {
$('#check_all').on('click', function(e) {
if ($(this).is(':checked', true)) {
$(".checkbox").prop('checked', true);
} else {
$(".checkbox").prop('checked', false);
}
});
$('.checkbox').on('click', function() {
if ($('.checkbox:checked').length == $('.checkbox').length) {
$('#check_all').prop('checked', true);
} else {
$('#check_all').prop('checked', false);
}
});
// jquery code for display array :
$("#hide").click(function() {
var items = [];
$("tr").each(function(i, r) {
if (i > 0 && $(r).find("input").first().prop("checked")) {
//sum = (((salary/24)*nbre)+premium)
let sum = (((parseInt($(r.cells[2]).text()) / 24) * parseInt($(r.cells[3]).text())) + parseInt($(r.cells[4]).find('input').val()));
items.push({
"matricule": r.cells[1].innerText,
"salary": r.cells[2].innerText,
"nbre": r.cells[3].innerText,
"premium": $(r.cells[4]).find('input').val(),
"sum": sum
})
}
});
console.log(items);
});
})
