Switch case is not working in Reactjs - forms

Question

I have a json and I'm trying to display a form using the json data. I tried to display the indexes using the Switch case, so based on the html control type the index will be displayed. Below is my code
var React = require('react');
var ReactDOM = require('react-dom');
var DATA = {
"indexList": [{
"Label": "Name",
"Type": "text",
"Regex": "",
"Default_Val": "",
"Values": {
"Key": "",
"Value": ""
},
"Validtion Msg": "",
"Script": "",
"Mandatory": "required",
"maxLength":"16",
"minLength":"7",
"format":"Alphanumeric",
"cssClassName": "form-control",
"Placeholder": ""
},
{
"Label": "Select Language",
"Type": "dropdown",
"Regex": "",
"Default_Val": "English",
"Values": [{
"Key": "option1",
"Value": "English"
},{
"Key": "option2",
"Value": "Spanish"
}],
"Validtion Msg": "",
"Script": "",
"Mandatory": "Y",
"maxLength":"",
"minLength":"",
"format":"",
"cssClassName": "form-control",
"Placeholder": ""
},
{
"Label": "Type",
"Field_Type": "radio",
"Regex": "",
"Default_Val": "",
"Values": [{
"Key": "option1",
"Value": "Form1"
}, {
"Key": "option2",
"Value": "Form2"
}, {
"Key": "option3",
"Value": "Form3"
},{
"Key": "option4",
"Value": "Form4"
},{
"Key": "option5",
"Value": "Form5"
}],
"Validtion Msg": "",
"Script": "",
"Mandatory": "Y",
"maxLength":"",
"minLength":"",
"format":"",
"cssClassName": "form-control",
"Placeholder": ""
}
]
};
var Menu = React.createClass({
renderForm: function () {
var data = DATA.indexList;
console.log(data);
return data.map(group =>{
return <div>
<label for={group.Label}>{group.Label}</label>
<div>
switch(group.Type) {
case 'text':
return <input className={group.cssClassName}
id={group.Label}
placeholder={group.Placeholder}
{group.Mandatory}/>
case 'dropdown':
return <select className={group.cssClassName}>
<option value="">{group.Placeholder}</option>
<option for="let values of group.Values.value">{values}</option>
</select>
case 'radio':
return <div className={group.Type}>
<div for="let value of group.Values">
<label><input
name="radios"/>{value}</label>
</div>
</div>
case 'chekbox'
return <div className={group.Type}>
<div for="let value of group.Values">
<label><input name="checkbox"/>{value}</label>
</div>
</div>
}
</div>
</div>
});
},
render: function() {
return (
<div className="container">
<br/>
<div className="panel panel-primary">
<div className="panel-heading">Form</div>
<div className="panel-body">
<form>
<div className="form-group">
<div className="col-xs-5">
{this.renderForm()}
<button type="button" className="btn btn-primary">Submit</button>
</div>
</div>
</form>
</div>
</div>
</div>
)}
});
module.exports = Menu
With the above code Im getting an error "Unexpexcted token" and the error is pointing towards the "case". Can anyone help to resolve the issue, Im new to react and Im not able to resolve this issue. Any syntax error in the code?

Answer 1

Because you forgot to put {}, use this:
<div>
{
}
To use any javascript code inside HTML element we need to use {}.
Note: We can't directly use if-else/switch statement inside JSX, use either ternary operator or call a function from JSX and use if-else/switch inside that.
Reference: http://reactjs.cn/react/tips/if-else-in-JSX.html
Check the working example:
var DATA = {
"indexList": [{
"Label": "Name",
"Type": "text",
"Regex": "",
"Default_Val": "",
"Values": {
"Key": "",
"Value": ""
},
"Validtion Msg": "",
"Script": "",
"Mandatory": "Y",
"maxLength":"16",
"minLength":"7",
"format":"Alphanumeric",
"cssClassName": "form-control",
"Placeholder": ""
},
{
"Label": "Select Language",
"Type": "dropdown",
"Regex": "",
"Default_Val": "English",
"Values": [{
"Key": "option1",
"Value": "English"
},{
"Key": "option2",
"Value": "Spanish"
}],
"Validtion Msg": "",
"Script": "",
"Mandatory": "Y",
"maxLength":"",
"minLength":"",
"format":"",
"cssClassName": "form-control",
"Placeholder": ""
},
{
"Label": "Type",
"Type": "radio",
"Regex": "",
"Default_Val": "",
"Values": [{
"Key": "option1",
"Value": "Form1"
}, {
"Key": "option2",
"Value": "Form2"
}, {
"Key": "option3",
"Value": "Form3"
},{
"Key": "option4",
"Value": "Form4"
},{
"Key": "option5",
"Value": "Form5"
}],
"Validtion Msg": "",
"Script": "",
"Mandatory": "Y",
"maxLength":"",
"minLength":"",
"format":"",
"cssClassName": "form-control",
"Placeholder": ""
}
]
};
var Menu = React.createClass({
_renderElement: function(group){
switch(group.Type){
case 'text':
return <input className={group.cssClassName}
id={group.Label}
placeholder={group.Placeholder}
required={group.Mandatory == 'Y'? true: false}/>
case 'dropdown':
return <select className={group.cssClassName}>
<option value="">{group.Placeholder}</option>
{group.Values.map(el => <option key={el.Key} for="let values of group.Values.value">{el.Value}</option>)}
</select>
case 'radio':
return <div className={group.Type}>
<div for="let value of group.Values">
{group.Values.map(el=> <label key={el.Value}><input
name="radios"/>{el.Value}</label>)}
</div>
</div>
case 'checkbox':
return <div className={group.Type}>
<div for="let value of group.Values">
<label><input name="checkbox"/>{value}</label>
</div>
</div>
}
},
renderForm: function () {
var data = DATA.indexList;
return data.map(group =>{
return <div>
<label for={group.Label}>{group.Label}</label>
<div>
{
this._renderElement(group)
}
</div>
</div>
});
},
render: function() {
return (
<div className="container">
<br/>
<div className="panel panel-primary">
<div className="panel-heading">Form</div>
<div className="panel-body">
<form>
<div className="form-group">
<div className="col-xs-5">
{this.renderForm()}
<button type="button" className="btn btn-primary">Submit</button>
</div>
</div>
</form>
</div>
</div>
</div>
)}
});
ReactDOM.render(<Menu/>, document.getElementById('app'))
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>

<div id='app'/>

Answer 2

swithc-case should be within braces
renderForm: function() {
var data = DATA.indexList;
console.log(data);
return data.map(group => {
return <div >
< label
for = {
group.Label
} > {
group.Label
} < /label> < div >{
switch (group.Type) {
case 'text':
return <input className = {
group.cssClassName
}
id = {
group.Label
}
placeholder = {
group.Placeholder
}
/>
case 'dropdown':
return;
}} < /div> < /div>
});
},
