为什么不创建全局变量而不是创建隐藏元素?
var categoryId;
$(document).on("click", ".open-DeleteDialog", function () {
// initialize category id
categoryId = $(this).data('id');
});
正在获取类别id值
$('#saveChanges').on('click', function() {
console.log(categoryId )
});
$(function() {
// global variable
var categoryId;
$(document).on("click", ".open-DeleteDialog", function () {
// initialize category id
categoryId = $(this).data('id');
});
$('#saveChanges').on('click', function() {
console.log(categoryId )
});
})
