首先尝试使用反引号(``)来清理 javascript 中的 html 代码以进行注释
function addNewRow() {
var tableRow = `
<tr>
<td>
<select
onchange="fillData(this)"
name="service[]"
class="form-control sherbimi"
aria-describedby="llojisherbimit" required>
<option selected="selected" value=""> Zgjedh opsionin </option>
<option value="5" class="sale-select">5</option>
</select>
</td>
<td><input type="text" id="pershkrimi" value="" class="form-control" name="description[]" required ></td>
<td>
<select name="unit[]" class="form-control unit">
<option value="">Zgjidh Njësine </option>
<option value="cope"> Copë </option>
<option value="dite">Ditë </option>
</select>
</td>
<td><input type="text" id="cmimi" class="form-control price" name="price[]" required></td>
<td><input type="text" class="form-control quantity" name="quantity[] required"></td>
<td><input type="text" class="form-control amount" name="amount[]" required></td>
<td><a href="#" class="btn btn-danger a-btn-slide-text remove"><span><strong>x</strong></span></td>
</tr>
`
$('.detail').append(tableRow);
}
对函数和变量使用正确的命名语法,例如 addnewrow 到 addNewRow,始终使用var,const或声明变量let。
php 代码的结果存储在 javascript 变量中,因为 php 代码只会在服务器端执行,如果您需要 php 的动态内容,您应该使用 ajax,否则它将无法工作。在你的例子中,它作为 php 工作,它回显将用于准备函数结果的 html 代码。
您的代码的问题是您没有传递正在更改的某些元素,而是尝试通过类选择器选择元素,该选择器始终默认为第一个选择器,而不是您需要做的是:
在 html 方面,使用如下参数调用函数 fillData this:
<table class="table table-responsive table-bordered table-hover">
<thead>
<th>Shërbimi</th>
<th>Përshkrimi</th>
<th>Njësia</th>
<th>Çmimi</th>
<th>Sasia</th>
<th>Total</th>
<th>
<button id="add" class="btn btn-primary" onclick="addNewRow()">+</button></th>
</thead>
<tbody class="detail">
<tr>
<td width="25%">
<select name="service[]" onchange="fillData(this)" class="form-control sherbimi" aria-describedby="llojisherbimit" required>
<option selected="selected" value="" disabled="disabled">Zgjedh Shërbimin</option>
<option value='1' class='sale-select'>1</option>
<option value='2' class='sale-select'>2</option>
<option value='3' class='sale-select'>3</option>
</select>
<div class="invalid-feedback">
Ju lutem plotësoni shërbimin.
</div>
</td>
<td width="30%" >
<input type="text" id="pershkrimi" value="" class="form-control" name="description[]" required >
<div class="invalid-feedback">
Ju lutem plotësoni përshkrimin.
</div>
</td>
<td width="15%">
<select name="unit[]" class="form-control" aria-describedby="llojinjesis" required>
<option value="">Zgjedh Njësin</option>
<option value='cope'> Copë </option>
<option value='dite'> Ditë </option>
</select>
<div class="invalid-feedback">
Ju lutem plotësoni njësin.
</div>
</td>
<td width="10%" >
<input type="text" id="cmimi" class="form-control price" name="price[]" required>
<div class="invalid-feedback">
Ju lutem plotësoni çmimin.
</div>
</td>
<td width="10%">
<input type="text" class="form-control quantity" name="quantity[]" required>
<div class="invalid-feedback">
Ju lutem plotësoni sasinë.
</div>
</td>
<td width="10%">
<input type="text" class="form-control amount" name="amount[]" required>
<div class="invalid-feedback">
Ju lutem plotësoni totalin.
</div>
</td>
<td>
<!-- <a href="#" class="btn btn-danger a-btn-slide-text remove">
<span><strong>x</strong></span></a> -->
</td>
</tr>
</tbody>
<tfoot>
<th></th>
<th></th>
<th></th>
<th></th>
<th></th>
<th style="text-align:center;" class="total">0<b></b></th>
<th></th>
</tfoot>
</table>
还要更改 addNewRow 函数,使其包含此变量(不要忘记使用您的版本,因为我从此处删除了 php 内容):
function addNewRow() {
var tableRow = `
<tr>
<td>
<select
onchange="fillData(this)"
name="service[]"
class="form-control sherbimi"
aria-describedby="llojisherbimit" required>
<option selected="selected" value=""> Zgjedh opsionin </option>
<option value="5" class="sale-select">5</option>
</select>
</td>
<td><input type="text" id="pershkrimi" value="" class="form-control" name="description[]" required ></td>
<td>
<select name="unit[]" class="form-control unit">
<option value="">Zgjidh Njësine </option>
<option value="cope"> Copë </option>
<option value="dite">Ditë </option>
</select>
</td>
<td><input type="text" id="cmimi" class="form-control price" name="price[]" required></td>
<td><input type="text" class="form-control quantity" name="quantity[] required"></td>
<td><input type="text" class="form-control amount" name="amount[]" required></td>
<td><a href="#" class="btn btn-danger a-btn-slide-text remove"><span><strong>x</strong></span></td>
</tr>
`
$('.detail').append(tableRow);
}
然后是 filldata 函数:
function fillData(element) {
var empid = element.value
$.ajax({
method:"POST",
url: 'sale_data.php',
dataType: "JSON",
data: 'empid='+ empid,
success: function(data) {
$('input[name="description[]"]').val(data.description);
$('input[name="price[]"]').val(data.price);
}
});
}
