我有一张看起来像这样的表
var dataW = [
{
taskName: 'WWWx',
standarDescription: 'WWW',
emp_comment: 'WW',
empRating: '1',
review_comment: '',
review_rating:'',
}
]
var Tablefortask = React.createClass({
getInitialState: function() {
return {data: dataW};
},
onChange: function (e) {
var employeeId = e.target.value;
alert(employeeId);
},
render: function() {
return (
<div className="border-basic-task col-md-12">
<div className="col-md-12">
<table className="table table-condensed table-bordered table-striped-col " id="table-data">
<thead>
<tr align="center">
<th>Task Name</th>
<th >Standard Discription of Task</th>
<th>Employee Comment</th>
<th >Employee Rating</th>
<th width="30%">Reviewer Comment</th>
<th >Reviewer Rating</th>
</tr>
</thead>
<TablefortaskList data={this.state.data} onChange={this.onChange} />
</table>
</div>
</div>
);
}
});
var TablefortaskList = React.createClass({
render: function() {
var commentNodes = this.props.data.map(function(comment) {
return (
<Addcontenttotable onChange= {this.props.onChange} taskName={comment.taskName} standarDescription={comment.standarDescription} emplComment={comment.emp_comment} empRating={comment.empRating} key={comment.id} reviewComment={comment.review_comment} reviewRating={comment.review_rating} >
</Addcontenttotable>
);
},this);
return (
<tbody>{commentNodes}</tbody>
);
}
});
var Addcontenttotable = React.createClass({
render: function() {
if(this.props.reviewComment=== "" && this.props.reviewRating === '' ){
return (
<tr><td>{this.props.taskName}</td>
<td>{this.props.standarDescription}</td>
<td>{this.props.emplComment}</td>
<td width="5%">{this.props.empRating}</td>
<td ><textarea
className="form-control"
name="empComment"
placeholder="Employee Comment"
/>
</td>
<td>
<select
className="form-control"
onChange={this.props.onChange}
data-placeholder="Basic Select2 Box" >
<option value="">Option</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</td>
</tr>
);
}
else {
return (
<tr><td>{this.props.taskName}</td>
<td>{this.props.standarDescription}</td>
<td>{this.props.emplComment}</td>
<td>{this.props.empRating}</td>
<td>{this.props.reviewComment}</td>
<td>{this.props.reviewRating}</td>
</tr>
);
}
}
});
ReactDOM.render(
<Tablefortask />,
document.getElementById('container')
);
这是一个小提琴LINK
我想要实现的是,
1。如果用户选择下拉列表,则应检查是否有评论评论,如果没有,则应突出显示评论部分。
2。同样如果用户写评论,它应该检查是否存在评级,如果不存在则应该高亮显示评级
我相信TextArea我不应该使用Onchange,因为onChange会调用我在TextArea中输入的每个字符
答案 0 :(得分:1)
你甚至不需要一个函数来做到这一点,只需根据道具设置类。
var textAreaClass = this.props.reviewComment === "" && this.props.reviewRating !== "" ? "highlight" : "";
var comboClass = this.props.reviewComment !== "" && this.props.reviewRating === "" ? "highlight" : "";
设置你的课程
<textarea
className={textAreaClass}
onChange={this.props.onChangeTextArea}
name="empComment"
placeholder="Employee Comment" />
<select
className={comboClass}
onChange={this.props.onChange}
data-placeholder="Basic Select2 Box" >
</select>
PD:您可以使用classNames库来处理条件classNames
