我正在尝试创建一个待办事项列表,在您完成一项任务后,
只有这样才能启用下一项任务(勾选完成)。
这是我到目前为止所拥有的:
/** @jsx React.DOM */
$(function(){
var tasks = [
{title: "Wake up"},
{title: "Eat dinner"},
{title: "Go to sleep"}
];
var Task = React.createClass({
getInitialState: function(){
return {locked:true, done:false}
},
handleClick: function(e){
this.setState({done: !this.state.done});
var selector = '.toggle[data-order="'+(this.props.order+1)+'"]';
this.setState({locked: true})
console.log(selector)
console.log($(selector).removeAttr("disabled"))
},
render: function() {
var locked;
//Fix first task to not be disabled
if(this.props.order == 0 && this.state.done === false)
locked = false;
else
locked = this.state.locked;
var done = this.state.done ? "Done":"Not done";
var classView = "task" + (this.state.done ? " done":" not-done");
return (
<div class="todo well well-sm" class={classView}>
<span class="description">{this.props.title}</span>
<button type="button" onClick={this.handleClick} data-order={this.props.order} disabled={locked} class="toggle btn btn-default btn-xs pull-right">
<span class="glyphicon glyphicon-unchecked"></span> Done
</button>
</div>
);
}
});
var TaskList = React.createClass({
render: function(){
var i = -1;
var taskNodes = this.props.data.map(function (task) {
return <Task title={task.title} order={++i} />;
});
return (
<div class="task-list">
{taskNodes}
</div>
);
}
});
var Guider = React.createClass({
render: function(){
return (
<div>
<TaskList data={this.props.data} />
</div>
);
}
});
React.renderComponent(<Guider data={tasks} />, document.body);
});
下一个按钮仍然没有被禁用,我觉得我做错了一般(不符合反应“禅”)。
顺便说一句:如何在不触发用户触发的情况下更改 dom 元素的状态?有什么我应该使用的 id 吗?
