How to get multiple values using JSTL tags?

Question

I have this button:

<button type="button" class="btn btn-danger" id="deleteuserbtn" value="${usr.idUser}" onclick="deleteUser(this.value)">Delete</button>

That calls the function deleteUser once the button is clicked.

I would like to know how to send more than one value at the same time.

For example, if I want to send the idUser and the userName, how can I do it?.

I tried this but it's not working:

<button type="button" class="btn btn-danger" id="deleteuserbtn" value="${usr.idUser, usr.userName}" onclick="deleteUser(this.value)">Delete</button>

I expect to receive the values in the same jsp page:

        function deleteUser(val1, val2) {
            alert(val1);
            alert(val2);
        }

Answer 1

You can simply pass your values under your function under '' quotes else it will give you error not defined.So your button code will look like below :

<button type="button" class="btn btn-danger" value="something" id="deleteuserbtn" onclick="deleteUser(this.value ,'${usr.idUser}','${usr.userName}')">
Delete</button>                                                              

Demo Code :

function deleteUser(val1,val2,val3){
alert("val :"+val1 +" "+val2+" "+val3);
}

<button type="button" class="btn btn-danger" id="deleteuserbtn" value="something" onclick="deleteUser(this.value,'${usr.idUser}','${usr.userName}')">
    Delete</button>
