如何在jQuery中为链接函数赋值链接函数

Question

例如，我想将链式流程分配到不同的变量中，并在不同的条件下使用它们。

var disable_btn = true;
var button_me = $('#contents.getsamplekit .sample-form .form #submit-btn-freeSample-me');
var button_disabled = button_me.attr("disabled",true).css("background","red"); // need to add more functions.
var button_enabled = button_me.removeAttr("disabled").css("background","green"); // need to add more functions here as well.
(disable_btn) ? button_disabled : button_enabled; 
]

Answer 1

您在分配变量时调用函数，而不是在测试disable_btn时调用函数。如果要等待，则必须定义新功能：

function button_disable(button) {
    button.attr("disabled", true).css("background", "red");
}
function button_enable(button) {
    button.removeAttr("disabled").css("background","green");
}
(disable_btn ? button_enable : button_disable)(button_me);
