display radio button as selected

[Dave Jamz]

Hi

I am trying to set the value of my radio buttons from my action form but in the jsp I am just seeing two unselected radio buttons.

I have tried both of the ways below in the jsp:

 <td width="30%"><input type="radio" name="testRadioButtons" value="${unitForm.testRadio eq true}" >Yes 2222</td>
 <td width="25%"><input type="radio" name="testRadioButtons" value="${unitForm.testRadio eq false}" >No 2222</td>
 
  
  <td width="30%"><input type="radio" name="${unitForm.testRadio}" value="true" >Yes 33</td>
 <td width="25%"><input type="radio" name="${unitForm.testRadio}" value="false" >No 33</td>


 

action form code:

private Boolean testRadio = false;
	
	 
	public Boolean getTestRadio() {
		return testRadio;
	}

	public void setTestRadio(Boolean testRadio) {
		this.testRadio = testRadio;
	}

I don't see any evidence that you are putting the checked attribute on any of the elements.

I was trying to set the value from the actionform

When private Boolean testRadio = false; I want the no radio button to be selected and when private Boolean testRadio = true; i would like the yes radio button selected

I don't understand what you are doing with the value attributes; those are usually static. But whatever, to cause a radio button to be checked, give it the checked attribute.

This is more along the lines of what I'd do:

<input type="radio" name="testRadioButtons" value="true" ${unitForm.testRadio ? 'checked':''}>Yes 2222
<input type="radio" name="testRadioButtons" value="false" ${not unitForm.testRadio ? 'checked':''}>No 2222</td>  

This will place the checked attribute on the appropriate radio element.

I'd also recommend making use of the label element to make your buttons better behaved.

Thanks

What do the question mark and colon do?

[Bear Bibeault]

ternary operator

You should review the EL specification.
