复制代码 代码如下:

//打印纸尺寸，单位MM

//http://en.wikipedia.org/wiki/ISO_216

var page = function() {

var A0 = { name: "A0", width: 841, height: 1189 }; //单位MM

var B0 = { name: "B0", width: 1000, height: 1414 }; //单位MM

var C0 = { name: "C0", width: 917, height: 1297 }; //单位MM

//获取前一个规格

function getPrefixSize(name) {

var list = name.split('');

var series = list[0];

var number = parseInt(list[1]);

if (!isNaN(number) && number > 0) {

return series + (number - 1);

}

}

//获取规格的尺寸

function getSize(name) {

if (name == "C7/6") {

return { name: "C7/6", width: 81, height: 162 };

}

var list = name.split('');

var series = list[0];

var number = parseInt(list[1]);

if (isNaN(number)) {

return;

}

if (number == 0) {

if (series == "A") { return A0; }

else if (series == "B") { return B0; }

else if (series == "C") { return C0; }

}

return { name: name, width: parseInt(getSize(getPrefixSize(name)).height / 2), height: parseInt(getSize(getPrefixSize(name)).width) };

}

return {

getSize: getSize

}

} ();

用法

复制代码 代码如下:

page.getSize('A4')
