下面是我用来在整个程序中创建范围对象的代码
function parseRangeString(id, range) {
var myRangeString = range;
var myRangeStringArray = myRangeString.split(/[\s]+/);
var myMax;
var myMin;
var myMinOp;
var myMaxOp;
var myMaxInc = false;
var myMinInc = false;
var op1;
var op2;
var cons1;
var cons2;
op1 = myRangeStringArray[0];
cons1 = parseFloat(myRangeStringArray[1]);
if (myRangeStringArray[2] != null) {
op2 = myRangeStringArray[3];
cons2 = parseFloat(myRangeStringArray[4]);
}
if (cons1 < cons2) {
myMin = cons1;
myMinOp = op1;
myMax = cons2;
myMaxOp = op2;
} else {
myMin = cons2;
myMinOp = op2;
myMax = cons1;
myMaxop = op1;
}
if (myMaxOp.indexOf('=') != -1) {
myMaxInc = true;
}
if (myMinOp.indexOf('=') != -1) {
myMinInc = true;
}
firstRange = new Range(id, myMin, myMax, myMinInc, myMaxInc); //gives back a range object
return firstRange;
}
现在我需要创建另一个将范围对象转换为字符串的函数,需要帮助,因为我被卡住了!

您可以覆盖javascript对象上的标准toString
函数,使其返回您想要的任何内容。考虑这个例子(demo):
var a = { some_property:'this could be coming from the user' }; // create a new object
a.toString = function(){
// in here, the "this" will point to the object in "a" variable. (well, at least mot of the times)
return this.some_property;
};
console.log(''+a); // force the object to string
如果您创建了大量这样的对象,请考虑使用prototype
来放置toString
函数,效率更高,MDN有great examples。

我想我每天都会给出相同的答案。 :)
JSON.stringify( range );
