javascript - jQuery 在单击按钮或 onchange 下拉菜单上运行相同的函数

Question

我有以下代码，该代码在单击按钮上运行良好，但我也希望它在下拉列表的更改事件上执行。这是

 $("select#search_status").change() //i want same execution for it do i need to duplicate whole code ?


$('.search-btn-cls').click(function () {
    var search_text = $('#search_text').val();

    search_val = true;
    initiatePagination();
    // ajaxSortPaginationSearch();
    // show_per_page();
    // getpagination();

    if (search_text.length > 2 || search_text.length < 1) {
        ajaxSortPaginationSearch();
        show_per_page();
        getpagination();
    } else {
        alert('Please enter minimum 3 serach character.');
        $('#search_text').focus();
    }

});

不要使用匿名函数进行事件处理，而是创建一个函数并在两种情况下调用它，即单击和更改时。

// Create a function.
function handleDropdown() {
    var search_text = $('#search_text').val();

    search_val = true;
    initiatePagination();
    // ajaxSortPaginationSearch();
    // show_per_page();
    // getpagination();

    if (search_text.length > 2 || search_text.length < 1) {
        ajaxSortPaginationSearch();
        show_per_page();
        getpagination();
    } else {
        alert('Please enter minimum 3 serach character.');
        $('#search_text').focus();
    }

}
// Now call the function.
$('.search-btn-cls').click(handleDropdown);
$("select#search_status").change(handleDropdown);
