ng-true-value非常量表达式

Question

i am printing checkbox value something following by php

<input type='checkbox' ng-false-value='' ng-true-value='$row->option'>

i am looping this dynamically, but getting following error https://docs.angularjs.org/error/ngModel/constexpr?p0=ngTrueValue&p1=Canel

in html this ng-true-value='$row->option' printing like ng-true-value="Canel" is there any way to do like this ng-true-value="'Canel'", thats mean doublequte then single quote then value then single quote then double quote (something like "'Canel'")

Answer 1

<?php
echo "<input type='checkbox' ng-false-value='' ng-true-value=\"'$row->option'\">";

If $row->option is test it will output:

<input type='checkbox' ng-false-value='' ng-true-value="'test'">
