如何在jQuery小部件上设置选项

Question

我正在尝试从Wijmo设置几乎UNDOCUMENTED复选框小部件的选项.这是小部件的代码:

(function ($) {
    "use strict";
    var checkboxId = 0;
    $.widget("wijmo.wijcheckbox", {
        _csspre: "wijmo-checkbox",
        _init: function () {
            var self = this,
                ele = self.element,
                o = self.options,
                checkboxElement, label, targetLabel, boxElement, iconElement;
            if (ele.is(":checkbox")) {
                if (!ele.attr("id")) {
                    ele.attr("id", self._csspre + checkboxId);
                    checkboxId += 1;
                }
                if (ele.parent().is("label")) {
                    checkboxElement = ele.parent()
                    .wrap("<div class='" + self._csspre + "-inputwrapper'></div>")
                    .parent()
                    .wrap("<div></div>").parent().addClass(self._csspre + " ui-widget");
                    label = ele.parent();
                    label.attr("for", ele.attr("id"));
                    checkboxElement.find("." + self._csspre + "-inputwrapper")
                    .append(ele);
                    checkboxElement.append(label);
                }
                else {
                    checkboxElement = ele
                    .wrap("<div class='" + self._csspre + "-inputwrapper'></div>")
                    .parent().wrap("<div></div>").parent()
                    .addClass(self._csspre + " ui-widget");
                }
                targetLabel = $("label[for='" + ele.attr("id") + "']");
//              if (targetLabel.length > 0) {
//                  checkboxElement.append(targetLabel);
//                  targetLabel.attr("labelsign", "C1");
//              }
                if (ele.is(":disabled")) {
                    self._setOption("disabled", true);
                }
                boxElement = $("<div class='" + self._csspre +
                "-box ui-widget ui-state-" +
                (o.disabled ? "disabled" : "default") +
                " ui-corner-all'><span class='" +
                self._csspre + "-icon'></span></div>");
                iconElement = boxElement.children("." + self._csspre + "-icon");
                checkboxElement.append(boxElement);
                ele.data("iconElement", iconElement);
                ele.data("boxElement", boxElement);

                boxElement.removeClass(self._csspre + "-relative")
                .attr("role", "checkbox")

                }
                ele.bind("click.checkbox", function (e) {

                    boxElement.removeClass("ui-state-focus").not(".ui-state-hover")

有人可以通过告诉我如何在小部件工厂创建的小部件上设置选项来帮助我.我找不到任何能给我建议的东西.

更新:

我发布了完整的代码.评论区域是我的评论.

Answer 1

查看插件(小部件)的源代码,看起来您只有一个可配置的选项参数.它被称为disabled你可以像这样使用它......

$(document).ready(function () {
    $(":input[type='checkbox']").wijcheckbox({
        disabled: true
    });
});

它可能在文档中没有提到,因为如果元素的disabled属性已在其他地方设置,则插件会自动将其设置为"true" .

if (ele.is(":disabled")) {
    self._setOption("disabled", true);
}

编辑基于OP对原始帖子的评论:

"...我检查了代码,我看到o = self.options, checkboxElement, label, targetLabel, boxElement, iconElement;如果我知道如何设置这些我就没事......"

逗号后的项目列表并不是任何部分o,self.options或任何用户可配置的选项或参数.它们只是插件内部的附加变量声明.

换句话说,这......

var self = this,
    ele = self.element,
    o = self.options,
    checkboxElement, label, targetLabel, boxElement, iconElement;

这只是速记(和更有效的代码)...

var self = this;
var ele = self.element;
var o = self.options;
var checkboxElement;
var label;
var targetLabel;
var boxElement;
var iconElement;

o 是表示插件的选项或参数的变量.
