如何在JavaScript中的if语句中指定多个条件 [英] How to specify multiple conditions in an if statement in javascript

问题描述

这就是我提到这两个的两个条件

Here is how I mention two conditions if this or this

if (Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')
    PageCount= document.getElementById('<%=hfPageCount.ClientID %>').value;
}

推荐答案

只需将它们添加在if语句的主括号内，例如

just add them within the main bracket of the if statement like

if ((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')) {
            PageCount= document.getElementById('<%=hfPageCount.ClientID %>').value;
}

从逻辑上讲，这也可以用更好的方式重写！ 这具有完全相同的含义

Logically this can be rewritten in a better way too! This has exactly the same meaning

if (Type == 2 && (PageCount == 0 || PageCount == '')) {
