How to split a string and get first words?
studentController.groovy
def student = {
def ex = new ArrayList()
ex[0]= "Steven | ABCDEF0123456"
ex[1]= "Steven | ABCDEF0123456"
//student's value
[studentlist:ex] //send to gsp
}
student.gsp
<g:each in="${studentlist}" status="i" var="stdnt">
<tr class="${(i % 2) == 0 ? 'odd' : 'even'}">
<td>${stdnt}</td> //i want this show "Steven"
<td>${stdnt}</td> // and this show ABCDEF0123456
</tr>
</g:each>
How can I get the first word and second word?
You want Java's String.split()
method:
List ex = "Steven | ABCDEF0123456".split('\\|')*.trim()
[studentlist:ex] //send to gsp
If you know there are only two items in the list, then you can reference them via studentlist[0]
and studentlist[1]
. It's a little unclear what you expect from the controller currently (a list of lists?):
<td>${studentlist[0]}</td>
<td>${studentlist[1]}</td>
