asp.net - 输入时的 Gridview 更新按钮

Question

有没有办法做到这一点。假设用户在 datagridview 的更新行中。他们只想按回车键并触发更新按钮，而不考虑他们在行中的位置。有没有办法做到这一点？我曾尝试弄乱标签顺序，但我可以将更新标签留在标签顺序之外，并在用户按 Enter 时使其更新吗？

Answer 1

是的，你可以用 jQuery 做到这一点。这是一种通用的方法，但是如果您发布标记，我可以为您定制它。无论如何，我对所有 .NET 应用程序都执行此操作，只是因为使用一个表单标记存在一般问题：

function initEnterKeyManagement() {
    //Remove Enter keys on all
    jQuery('input').keypress(function (e) {
        var code = null;
        code = (e.keyCode ? e.keyCode : e.which);
        return (code == 13) ? false : true;
    });

    var oCurrForm = jQuery('#container with fields');
    var oCurrButton = oCurrForm.find('#button you want to trigger');

    //Submit Buttons
    if (oCurrButton && oCurrButton.length) {
        //Each field
        jQuery.each(oCurrForm.find('input'), function () {
            jQuery(this).keypress(function (e) {
                var code = null;
                code = (e.keyCode ? e.keyCode : e.which);
                if (code == 13)
                    oCurrButton.trigger('click');
            });
        });
    }
}

基本上，您要删除回车键的默认效果，然后重新分配它以执行您想要的操作。在上述情况下，单击（）。
