问题描述
Really new to JavaScript and html. I would like to be able to create a function that checks if the input field is filled out and if so it closes down the field set. I have written the closing field-set part I just cant figure out how to validate whether the user has filled out the input fields.
<fieldset>
<legend><a href="#" onclick="doit()">Tell us who you are</a></legend>
<div id="one">
<div>
<label> An injured worker</label>
<input type="radio" name="group1" value="injure"/>
</div>
<div>
<label> An employer </label>
<input type="radio" name="group1" value="employee"/>
</div>
<div>
<label> An injured worker and employer </label>
<input type="radio" name="group1" value="both"/>
</div>
</div>
</fieldset>
我的尝试：
函数doit（）{
if（document.getElementById（'one'）。style.display =='none'）{
document.getElementById（'one'）。style.display ='block';
} else {
document.getElementById（'one'） .style.display ='none';
}
}
What I have tried:
function doit() {
if(document.getElementById('one').style.display == 'none'){
document.getElementById('one').style.display = 'block';
} else {
document.getElementById('one').style.display = 'none';
}
}
