javascript - 我的验证不适用于添加的行和自动编号
问题描述
我有一个可以添加行和自动编号的功能。当您单击“添加行”按钮时,添加行起作用,当您按Ctrl+Enter键时,当有 2 行或更多行时,自动编号起作用。我的问题是,我的验证不适用于我的自动编号。
例如:当我在文本框中手动输入“1”时,它可以工作。但是当我进行自动编号时,“不好”不会出现在我的第二个文本框中。
有什么我错过的吗?任何帮助将不胜感激。
//this is for adding rows
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" name="entryCount" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" value="" class="form" type="number" /> <span class="email_result"></span></td>"' +
'<td><input type="button" class="removerow" id="removerow' + rowIndex + '" name="removerow' + rowIndex + '" value="Remove"/></td>';
$("#applicanttable > tbody > tr:last").after(newRow);
});
//this is for my validation
$(document).on('change', 'input[name*=lightBand]', function() {
var lightBand1 = $(this).val(); //get value
var selector = $(this) //save slector
selector.next('.email_result').html("") //empty previous error
if (lightBand1 != '') {
/*$.ajax({
url: "<?php echo base_url(); ?>participant/check_number_avalibility",
method: "POST",
data: {
lightBand1: lightBand1
},
success: function(data) {*/
selector.next('.email_result').html("NOT GOOD"); //use next here ..
/* }
});*/
}
});
// this is for autonumbering when ctrl+enter is pressed.
const inputs = document.querySelectorAll(".form");
document.querySelectorAll(".form")[0].addEventListener("keyup", e => {
const inputs = document.querySelectorAll(".form");
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
inputs.forEach((inp, i) => {
if (i !== 0) {
inp.value = ++value;
}
})
}
});
Add a row and type any number at number textbox column and press ctrl+enter. You'll see the "Not good" is not working on added rows. It'll only work if you enter the number manually per row.

解决方案
您可以调用您的事件处理程序,即:change
每当您通过自动编号更改输入值时。因此,使用$(this).trigger("change")
wherethis
指代更改值的输入。
演示代码:
$("#addrow").on('click', function() {
let rowIndex = $('.auto_num').length + 1;
let rowIndexx = $('.auto_num').length + 1;
var newRow = '<tr><td><input class="auto_num" type="text" name="entryCount" value="' + rowIndexx + '" /></td>"' +
'<td><input name="lightBand' + rowIndex + '" value="" class="form" type="number" /> <span class="email_result"></span></td>"' +
'<td><input type="button" class="removerow" id="removerow' + rowIndex + '" name="removerow' + rowIndex + '" value="Remove"/></td>';
$("#applicanttable > tbody > tr:last").after(newRow);
});
//this is for my validation
$(document).on('change', 'input[name*=lightBand]', function() {
var lightBand1 = $(this).val(); //get value
var selector = $(this) //save slector
selector.next('.email_result').html("") //empty previous error
if (lightBand1 != '') {
/*$.ajax({
url: "<?php echo base_url(); ?>participant/check_number_avalibility",
method: "POST",
data: {
lightBand1: lightBand1
},
success: function(data) {*/
selector.next('.email_result').html("NOT GOOD"); //use next here ..
/* }
});*/
}
});
// this is for autonumbering when ctrl+enter is pressed.
$(document).on('keyup', '.form', function(e) {
let value = parseInt(e.target.value);
if ((e.ctrlKey || e.metaKey) && (e.keyCode == 13 || e.keyCode == 10)) {
//loop through all values...
$(".form").each(function(i) {
if (i !== 0) {
$(this).val(++value); //assign new value..
$(this).trigger("change") //call your change event to handle further...
}
})
}
})
Add a row and type any number at number textbox column and press ctrl+enter. You'll see the "Not good" is not working on added rows. It'll only work if you enter the number manually per row.
