我知道以下if / else语句会提示“不相等！”......
if (true) {
alert("They are not equal!");
} else {
alert("They are equal!");
}
但如果我用......替换我的病情会怎样？

我的问题是：第二个例子中的条件是什么？
它只是说“真实” - 这是什么（需要什么是真的）？
这是否意味着它返回'true'所有的时间？
答案 0 :(得分：0)
示例：
if(file.size > 100) { // will not be true always, it's depends of each specific file size
alert("Your size file is bigger than permitted!");
} else {
alert("Your file loading...");
}
从您的代码中删除 true ，放置比较条件。
示例：
var a = "ok";
var b = "ok";
var c = "other text";
if(a==b){ // will be true
alert("first condition will execute a code");
} else {
alert("not executed");
}
if(a==c){ // condition will be false
alert("not executed");
} else {
alert("else will execute a code...");
}
