使用带有knockoutjs的prettyCheckable插件2.1检查数据绑定不起作用 [英] using prettyCheckable plugin with knockoutjs 2.1 checked data-binding doesn't work

问题描述

我正在使用prettyCheckable jquery插件使我的复选框和单选按钮看起来很漂亮，如果我使用data-bind =checked：dateMode它不起作用，因为插件隐藏了实际的复选框并使其自己的覆盖html来复选复选框/收音机，因此当我检查收音机或复选框并更新模型中的值时，knockoutjs lib无法识别。我知道如果我不使用prettyCheckable插件我的代码工作正常，所以不要告诉我我的模型或数据绑定代码搞砸了。我对此进行了测试。

I am using the prettyCheckable jquery plugin to make my checkboxes and radio buttons look pretty and if I use the data-bind="checked: dateMode" it doesn't work because the plugin hides the actual checkbox and makes it's own override html to pretty up the checkbox/radio, therefore the knockoutjs lib doesn't recognize when I check the radio or checkbox and update the value in the model. I know my code works fine if I don't use prettyCheckable plugin, so don't tell me my model or data binding code is messed up. I tested this.

这是我的部分查看代码。

Here is my partial view code.

<div id="DatesChooser" class="span5 pull-left">
    <h4><i class="icon-calendar"></i>Dates</h4>
    <input type="radio" name="Date" value="All" data-label="All Available" data-bind="checked: dateMode" /><br />
    <input type="radio" name="Date" value="Range" data-label="Range" data-bind="checked: dateMode" />
    <div data-bind="visible: dateMode() == 'Range'">
        <input type="text" id="FromYear" placeholder="1970" /> to
        <input type="text" id="ToYear" placeholder="2012" /><br />
        <div id="Date-Slider" class="ui-slider ui-slider-horizontal ui-widget ui-widget-content ui-corner-all">
            <div id="Date-Slider-Bar" class="ui-slider-range ui-widget-header" style="left: 0%; width: 100%;"></div>
            <a class="ui-slider-handle ui-state-default ui-corner-all" href="#" style="left: 0%;"></a>
            <a class="ui-slider-handle ui-state-default ui-corner-all" href="#" style="left: 100%;"></a>
        </div>
    </div>
</div>

这是我的淘汰模特：

function searchVm() {
    var self = this;
    self.dateMode = ko.observable("All");
    self.startSearch = function () { alert(self.dateMode()); };
};

我初始化了像这样的prettyCheckable：

And I initialize the prettyCheckable stuff like this :

$('input:checkbox').prettyCheckable();
$('input:radio').prettyCheckable();

这是代码在PrettyCheckable插件修改后呈现的内容，请注意输入样式是如何'display：none'：

Here is what the code gets rendered as after the prettyCheckable plugin modifies it, notice how the input style is 'display:none' :

<div id="DatesChooser" class="span5 pull-left">
    <div class="clearfix prettyradio labelright blue">
        <input type="radio" data-bind="checked: dateMode" data-label="All Available" value="All" name="Date" style="display: none;" checked="checked">
        <a class="checked" href="#"></a>
        <label for="undefined">All Available</label>
    </div>
    <br>
    <div class="clearfix prettyradio labelright blue">
        <input type="radio" data-bind="checked: dateMode" data-label="Range" value="Range" name="Date" style="display: none;">
        <a class="" href="#"></a>
        <label for="undefined">Range</label>
    </div>
    <div data-bind="visible: dateMode() == 'Range'" style="display: none;">
        <input id="FromYear" class="placeholder" type="text" placeholder="1970">
to
        <input id="ToYear" class="placeholder" type="text" placeholder="2012">
        <br>
        <div id="Date-Slider" class="ui-slider ui-slider-horizontal ui-widget ui-widget-content ui-corner-all">
            <div id="Date-Slider-Bar" class="ui-slider-range ui-widget-header" style="left: 0%; width: 100%;"></div>
            <a class="ui-slider-handle ui-state-default ui-corner-all" style="left: 0%;" href="#"></a>
            <a class="ui-slider-handle ui-state-default ui-corner-all" style="left: 100%;" href="#"></a>
            <div class="ui-slider-range ui-widget-header" style="left: 0%; width: 100%;"></div>
        </div>
    </div>
 </div>

推荐答案

漂亮的可检查触发器更改复选框上的事件，但Knockout查找单击事件。这可以通过更改 prettyCheckable.js 第46-54行来修复。原文：

Pretty Checkable triggers change events on the checkboxes, but Knockout looks for click events. This can be fixed with a change in prettyCheckable.js lines 46-54. Original:

    if (input.attr('checked') !== undefined) {
      input.removeAttr('checked').change();
    } else {
      input.attr('checked', 'checked').change();
    }

更改：

    if (window.ko) {
      ko.utils.triggerEvent(input[0], 'click');
    } else {
      input.click();
    }

如果你使用jQuery的，Knockout也行不通单击触发器功能。您必须使用Knockout的 triggerEvent ，如上所述。

Knockout also won't work if you use jQuery's click trigger function. You must use Knockout's triggerEvent as above.
