Ajax 文本字段:获取文本字段的 class 并更改默认值
Ajax text field: getting a class of a text field and changing the default value
目标:点击
时更改 current_category_id
的值
我希望更改值的输入标签:
<input type="text" id="current_category_id" class="current_category_id" value="1">
按钮,此处的值根据单击的行而变化
<button type="button" value="${cat.category_id}" class="category_sort btn float-left" data-toggle="modal" data-target="#createCategory">${cat.category_name} (${cat.category_id})</button>
此代码未定义
$(document).on('click', '.category_sort', function (e) {
e.preventDefault();
var new_category_id_sort = $(this).val();
document.getElementById('current_category_id').value=e.new_category_id_sort;
);
如何修复我的 document.getElementById?
使用查询选择器
$(document).on('click', '.category_sort', function (e) {
e.preventDefault();
//change value to sort group
var new_category_id_sort = $(this).val();
var a = document.querySelector('.current_category_id').value;
document.querySelector('.current_category_id').value = new_category_id_sort;
fetchgroup();
});
