Question

这里是我的习惯杂草法:

(function($){
    $.fn.extend({
        getmyValue : function(){
        return this.each(function() {
                return this.myVal;
        });
        },
        initPlugin : function(){
        return this.each(function() {
                this.myVal= Some results ;
        });
        }
    });
})(jQuery);

一、导言

$(document).ready(function() {

$("#div").initPlugin();
alert($("#div").getmyValue());
});

返还价值不是假定的便衣物,而物体(“#div”美元)则退还。

回归链条为什么不发挥作用?

Answer 1

由于<代码>each的回报值是您称之为each的标的。 docs链接。

从你的法典中看,你真想做什么? 第一个包含内容的<条形码> 包括所有要素的<密码>myVal的数值?

您指的是<条码>。贵重物品存放在 j子里:

getmyValue : function(){
    // Here, `this` is the jQuery instance on which `getmyvalue` was called
    return this.myVal;
},

如果您对第一个要素(指它作为典型情况下的原始多功能元素):

getmyValue : function(){
    // Here, `this` is the jQuery instance on which `getmyvalue` was called.
    // `this[0]` is the first matched element (a raw DOM element, typically).
    // Note we check before accessing it to see if it s there, since a jQuery
    // instance may have matched zero elements.
    return this[0] ? this[0].myVal : undefined;
},

如果您指的是一系列<代码>myVal 所有相应要素的数值(在典型情况下,这些数值为:

getmyValue : function(){
    // Here, `this` is the jQuery instance on which `getmyvalue` was called.
    return this.map(function() {
            // Here, though, `this` one of the elements wrapped by the jQuery,
            // instance typically a raw DOM element. (Each of them in a loop.)
            return this.myVal;
    }).get();
},

...which uses map to get a jQuery-wrapped array of the values, and then get to get the raw array from it.

Answer 2

页: 1

getmyValue: function() {
    return this.myVal;
}

Answer 3

<代码>。请用<代码>替换。之后,你的法典将重新列出限定的价值观清单。
