从文本文件的逗号分隔文本创建 javascript 中的下拉列表
creating a drop down list in javascript from comma delimited text of a text file
我有一个包含数据的文本文件(VMS.txt)
A,B,C,D
所以我只想要这个逗号分隔的文本作为下拉列表的内容,因为我对 javascript 不是很熟悉,任何人都可以帮助我。
这是我的代码 (Index.php)
<script>
$(document).ready(function(){
$(document).on('click', '.add', function(){
var html = '';
html += '<tr>';
html += '<td><input type="text" name="VMName[]" class="form-control Vmname" /></td>';
html += '<td><select name="Type[]" id="VMName" class="form-control type"><option value="base" >Select Type</option>';
html +='</select>';
html += '<td><button type="button" name="remove" class="btn btn-danger btn-sm remove"><span class="glyphicon glyphicon-minus"></span></button></td></tr>';
$('#item_table').append(html);
});
$(document).on('click', '.remove', function(){
$(this).closest('tr').remove();
});
});
</script>
所以在这里,当我单击添加按钮时,它显示类型为下拉列表,我想要 A、B、C 作为该下拉列表的内容,我尝试了所有方法,我只需要有人帮助。请帮我解决这个问题。
使用“fetch”加载文本文件的内容:
fetch('http://localhost/VMS.txt')
.then(response => response.text())
.then((data) => {
console.log(data)
}
