Question

我正在尝试使用Knockout在显示模板中显示包含链接和mailto的表格。我还是新来的，我要事先道歉！

这是我的显示模板最初的原因：

<script type="text/template" id="customerSearchDisplayTemplate">
    <td class="hiddenId">{0}</td>
    <td><a href="/wrenchsciencewebadmin2/UserManager/Customer/CustomerEditor.aspx?CustomerID={1}">{1}</a></td>
    <td><a href="mailto:{2}">{2}</a></td>
    <td>{3}</td>
    <td>{4}</td>
    <td>{5}</td>
    <td>{6}</td>     
    <td>{7}</td>
    <td><a href="/wrenchsciencewebadmin2/Common/PopupWindows/CustomerNotes.aspx?customerid={8}">{8}</a></td>                     
</script>

这是我到目前为止，减去mailto AND链接：

<script type="text/template" id="customerSearchDisplayTemplate">
    <tr>
        <td class = "hiddenId"><span data-bind="text: customerSearchID"/></td> 
        <td><span data-bind="text: fullName" /></td>
        <td><span data-bind="text: primaryEmail" /></td>
        <td><span data-bind="text: secondaryEmail" /></td>
        <td><span data-bind="text: homePhone" /></td>
        <td><span data-bind="text: workPhone" /></td>
        <td><span data-bind="text: mobilePhone" /></td>
        <td><span data-bind="text: lastLogonDate" /></td>
        <td><span data-bind="text: wsNotes" /></td>            
    </tr>
</script>

使用attr属性中的text和data-bind属性，如下所示：

<script type="text/template" id="customerSearchDisplayTemplate">
    <tr>
        <td class = "hiddenId"><span data-bind="text: customerSearchID"/></td> 
        <td><span data-bind="text: fullName" /></td>
        <td>
            <span>
                <a data-bind="text: primaryEmail, 
                              attr: {href: 'mailto:'+primaryEmail()}" />
            <span/>
        </td>
        <td>
            <span>
                <a data-bind="text: secondaryEmail, 
                              attr: {href: 'mailto:'+secondaryEmail()}" />
            <span/>
        </td>
        <td><span data-bind="text: homePhone" /></td>
        <td><span data-bind="text: workPhone" /></td>
        <td><span data-bind="text: mobilePhone" /></td>
        <td><span data-bind="text: lastLogonDate" /></td>
        <td><span data-bind="text: wsNotes" /></td>            
    </tr>
</script>

确保在绑定attr即primaryEmail（）时通过函数语法访问电子邮件，否则它将返回函数定义而不是值。

<div data-bind="template: { name : 'customerSearchDisplayTemplate'}"></div>

<script type="text/template" id="customerSearchDisplayTemplate">
    <tr>
        <td class="hiddenId">
            <span data-bind="text: customerSearchID"/>
        </td> 
        <td><span data-bind="text: fullName" /></td>
        <td>
            <a data-bind="text: primaryEmail, 
                          attr: { href : 'mailto:'+primaryEmail() }" />
        </td>
        <td>
            <a data-bind="text: secondaryEmail, 
                          attr: { href : 'mailto:'+secondaryEmail() }"/>
        </td>
        <td><span data-bind="text: homePhone" /></td>
        <td><span data-bind="text: workPhone" /></td>
        <td><span data-bind="text: mobilePhone" /></td>
        <td><span data-bind="text: lastLogonDate" /></td>
        <td><span data-bind="text: wsNotes" /></td>            
    </tr>
</script>

如果你想一直使用MVVM，最好尽量让你的视图变得愚蠢：

<a data-bind="text: primaryEmail, attr: {href: primaryEmailMailtoLink}"></a>

然后在视图模型上创建一个计算的observable：

var ViewModel = function() {
    var self = this;

    // Observable property:
    self.primaryEmail = ko.observable('foo@bar.com');

    // Dependent observable:
    self.primaryEmailMailtoLink = ko.computed(function() {
            return 'mailto: ' + self.primaryEmail();
    };

    // Etc. (rest of your view model)
}
