我要显示这样的页面:
但是当我想使用此jQuery / JavaScript方法使其成为动态表单以创建动态受控输入表单时:
https://jsfiddle.net/aaki/hMJEy/1/
它变成这样:
我可以知道如何使用它来调整布局吗?
代码如下:
<form onSubmit={this.addTodo}>
<div class="multi-field-wrapper">
<div class="multi-fields">
<div class="multi-field">
<Button
type="submit"
className="btn show-modal"
onClick={() =>
this.setState({
showModal: !showModal
})
}
>
Send Email
</Button>
<Button
type="submit"
className="btn show-portal"
onClick={() =>
this.setState({
showPortal: !showPortal
})
}
>
Send SMS
</Button>
<Modal
header="Send Email"
open={showModal}
onClose={() =>
this.setState({
showModal: false
})
}
>

我尝试将“ multifield-wrapper”类名放在“表单”之前,然后显示可以像第一个图像一样,但是问题是当单击“添加字段”按钮时它无法添加动态表单,并且它什么也不做。我可以知道如何解决这个问题吗?如果您知道该怎么做,也可以提供示例代码并附带说明吗?这是因为我仍在学习如何使用React进行操作,谢谢。
更新代码
我可以通过将javascript放在表单中来将所有文本框都放在一行中,但是问题是当我在下一行中再添加一行时,文本框显示如下所示:
代码如下:
<form onSubmit={this.addTodo}>
<div className="row">
<div className="multi-field-wrapper">
<div className="multi-fields">
<div className="multi-field">
<div className="col-md-2 is-small">
<select onChange={this.handleTopicChange} required>
<option>Select topic</option>
{
this.state.topicData.map((item, index) =>
<option key={item.topic} value={this.state.topic}>{item.topic}</option>
)
}
</select>
</div>
<input className="col-md-2" type="text" placeholder="temperature" value="temperature" disabled/>
<div className="col-md-1">is</div>
<div className="select col-md-2 is-small">
<select id="selColor" value={this.state.selectedOption} onChange={this.handleChange}>
<option value="equal">Equal to</option>
<option value="notequal">Not equal to</option>
<option value="greater_than">Greater than</option>
<option value="smaller_than">Less than</option>
<option value="goe">Greater than or equal to</option>
<option value="loe">Less than or equal to</option>
</select>
</div>
<input id="test1" className="hideable col-md-1" type="text" value={this.state.equal} onChange={this.handleEqualChange} />
<input id="test2" className="hideable col-md-1" type="text" value={this.state.notequal} onChange={this.handleNotEqualChange} />
<input id="test3" className="hideable col-md-1" type="text" value={this.state.greater_than} onChange={this.handleGreaterThanChange} />
<input id="test4" className="hideable col-md-1" type="text" value={this.state.smaller_than} onChange={this.handleSmallerThanChange} />
<input id="test5" className="hideable col-md-1" type="text" value={this.state.goe} onChange={this.handleGOEChange} />
<input id="test6" className="hideable col-md-1" type="text" value={this.state.loe} onChange={this.handleLOEChange} />
<button type="button" className="remove-field col-md-2">Remove</button>
<button type="button" className="add-field col-md-2">Add field</button>
</div>
</div>
</div>
</div>
</form>
第一行就可以了:
添加下一行时,显示如下:
我可以知道如何解决这个问题吗?谢谢。

您应该将所有div像这样排成一行
System.ArgumentException: Keyword not supported: 'data source'.

您可以使用表格行类
<div className="form-row">
如果要在同一行中包含两个元素
<div className="form-row">
<div className="form-group col-md-6">
<label >email</label>
<input type="text"/>
</div>
<div className="form-group col-md-6">
<label>message</label>
<input type="text" />
</div>
</div>
如果您想连续输入一个输入
<div className="form-group col-md-12">
<label >email</label>
<input type="text"/>
希望对您有帮助
