我目前正在使用knokcout js渲染视图。
HTML:
<div data-bind="template: {data: {ui: uistate, action: actionHandler }, afterRender: doStuff}">
<custom-comp params="onclick: action.print, shouldShow: ui.showPrint">
</custom-comp>
</div>
custom-comp是我的自定义组件,用于呈现现有数据并执行其他操作。
脚本:
this.doStuff= function(elements) {
console.info(elements);
}
但是,即使自定义组件获取了数据,并且一切正常运行,它仍然会引发错误:
Uncaught ReferenceError: action is not defined
