It is important to run update.php. Drupal 6.14 includes database changes (added indexes and some column type changes to fit the stored data better).
记得执行update.php。
var a = 100;
function testResult(){
var b = 2 * a;
var a = 200;
var c = a / 2;
alert(b);
alert(c);
}
testResult()
输出的是什么呢?
开始我觉得应该是; 200 和 100, 结果 确实NaN和100。
