我有一个与设计相关的问题。
我有添加产品的账单。每行添加一个产品。每行图像添加一个产品
添加产品时,我还会在"保修"列中显示其保修:
所选产品在保修栏中显示保修
但是当我添加任何其他产品时,我无法显示其保修。无法在后续产品中显示保修
我的 HTML 下拉选项是动态出现的:
<tbody style="border: 1px solid rgba(0,0,0,0.35); height: 34px; line-height: 34px;">
<tr class="text-center">
<td>
<select id="myDropdown" name="bill_product[]" onChange="dropdownTip(this.value)">
<option disabled selected value="">Select Product</option>
<option id="1" value="31/01/2020">Product #1</option>
<option id="2" value="31/01/2030">Product #2</option>
<option id="3" value="31/01/2040">Product #3</option>
</select>
</td>
<td>
<input name="txtbox" type="text" id="txtbox" />
</td>
<td>
<button type="button" class="btn btn-danger btn-xs disabled">
<i class="fa fa-times"></i>
</button>
</td>
</tr>
</tbody>
我的JS用于在账单中添加行:
$(document).ready(function () {
var counter = 0;
$("#addrow").on("click", function () {
var newRow = $("<tr class='text-center'>");
var cols = "";
cols += '<td><select name="bill_product[]"><option disabled selected value="">Select Product</option><cms:pages masterpage="product.php"><option value="<cms:show k_page_id />"><cms:show k_page_title /></option></cms:pages></select></td>';
cols += '<td><input type="text" id="txtbox" name="txtbox" /></td>';
cols += '<td><button type="button" class="ibtnDel btn btn-danger btn-xs"><i class="fa fa-times"></i></button></td>';
newRow.append(cols);
$("table.order-list").append(newRow);
counter++;
});
$("table.order-list").on("click", ".ibtnDel", function (event) {
$(this).closest("tr").remove();
counter -= 1
});
});
显示保修结束日期的"我的代码":
$(document).ready(function() {
$("#myDropdown").change(function() {
var selectedValue = $(this).val();
$("#txtbox").val(selectedValue);
});
});
问题:我无法在第一个产品之后的任何产品上显示保修日期的值。
请帮忙。
PS:我正在使用CouchCMS将我的值动态带到选择的选项标签。
提出的解决方案,顺便说一下,我摆脱了非本机JS,它允许它适合任何解决方案:
<tbody style="border: 1px solid rgba(0,0,0,0.35); height: 34px; line-height: 34px;">
<tr class="text-center">
<td>
<select id="myDropdown" name="bill_product[]" onChange="dropdownTip(this.value)">
<option disabled selected value="">Select Product</option>
<option id="1" value="31/01/2020">Product #1</option>
<option id="2" value="31/01/2030">Product #2</option>
<option id="3" value="31/01/2040">Product #3</option>
</select>
</td>
<td>
<input name="txtbox" type="text" id="txtbox" />
</td>
<td>
<button type="button" class="btn btn-danger btn-xs disabled">
Delete
</button>
</td>
</tr>
</tbody>
// Line removal
let delBtns = document.querySelectorAll(".del-btn");
[].forEach.call(delBtns, function(delBtn){
delBtn.addEventListener('click', function(event){
let line = event.target.dataset.line;
let lineToRemove = document.querySelector("#line-"+line);
lineToRemove.remove();
})
});
// Input update
let productDropDowns = document.querySelectorAll("select");
[].forEach.call(productDropDowns, function(dropDown){
dropDown.addEventListener('change', function(event){
let line = event.target.dataset.line;
document.querySelector('#line-'+line+' input').value = event.target.value;
})
});
// New line button
let count = 0;
let newLineButton = document.querySelector("#newLineTrigger");
newLineButton.addEventListener('click', function(){
count++;
let tableBody = document.querySelector('tbody');
let newLine = document.createElement('tr');
newLine.id = 'line-' + count;
tableBody.appendChild(newLine);
newLine = document.querySelector('#line-' + count);
let col1 = document.createElement('td');
let select = document.createElement('select');
select.id = 'drop' + count;
select.dataset.line = count;
select.addEventListener('change', function(event){
let line = event.target.dataset.line;
document.querySelector('#line-'+line+' input').value = event.target.value;
})
for(let i=0; i<3; i++){
let option = document.createElement('option');
option.value = i;
option.innerText = 'option ' + i;
select.appendChild(option);
}
col1.appendChild(select);
let col2 = document.createElement('td');
let textBox = document.createElement('input');
textBox.id = 'textBox'+count;
textBox.name = 'textBox'+count;
col2.appendChild(textBox);
let col3 = document.createElement('td');
let newDelBtn = document.createElement('button');
newDelBtn.className = "del-btn";
newDelBtn.dataset.line = count;
newDelBtn.innerText = "Delete";
newDelBtn.addEventListener('click', function(event){
let line = event.target.dataset.line;
let lineToRemove = newLine;
lineToRemove.remove();
});
col3.appendChild(newDelBtn);
newLine.appendChild(col1);
newLine.appendChild(col2);
newLine.appendChild(col3);
tableBody.appendChild(newLine);
});
我没有看到添加行的触发环元素"#addrow"。你能更新小提琴以包含这个按钮吗?
所有保修输入字段的 id 都相同,即"txtbox"。您可以使用计数器变量为所有保修字段提供单独的 ID。
