JS生成一维码(条形码)功能示例

1、js代码：(function() {if (!exports) var exports = window;var BARS    = [212222,222122,222221,121223,121322,131222,122213,122312,132212,221213,221312,231212,112232,122132,122231,113222,123122,123221,223211,221132,221231,213212,223112,312131,311222,321122,321221,312212,322112,322211,212123,212321,232121,111323,131123,131321,112313,132113,132311,211313,231113,231311,112133,112331,132131,113123,113321,133121,313121,211331,231131,213113,213311,213131,311123,311321,331121,312113,312311,332111,314111,221411,431111,111224,111422,121124,121421,141122,141221,112214,112412,122114,122411,142112,142211,241211,221114,413111,241112,134111,111242,121142,121241,114212,124112,124211,411212,421112,421211,212141,214121,412121,111143,111341,131141,114113,114311,411113,411311,113141,114131,311141,411131,211412,211214,211232,23311120], START_BASE = 38, STOP    = 106 ;function code128(code, barcodeType) {if (arguments.length<2)barcodeType = code128Detect(code);if (barcodeType=='C' && code.length%2==1)code = '0'+code;var a = parseBarcode(code, barcodeType);return bar2html(a.join('')) + '' + code + '';}function bar2html(s) {for(var pos=0, sb=[]; pos"+nrCode) );};bars.add(START_BASE + barcodeType.charCodeAt(0));for(var i=0; i106) throw new Error("Unrecognized character ("+code+") at position "+i+" in code '"+barcode+"'.");bars.add( converted );}bars.push(BARS[bars.check % 103], BARS[STOP]);return bars;}var fromType = {A: function(charCode) {if (charCode>=0 && charCode<32) return charCode+64;if (charCode>=32 && charCode<96) return charCode-32;return charCode;},B: function(charCode) {if (charCode>=32 && charCode<128) return charCode-32;return charCode;},C: function(charCode) {return charCode;}};//--| Exportexports.code128 = code128;
})();
/*showDiv：代表需要显示的divID，textVlaue ： 代表需要生成的值，barcodeType：代表生成类型(A、B、C)三种类型
*/
function createBarcode(showDiv,textValue,barcodeType){var divElement = document.getElementById(showDiv);divElement.innerHTML = code128(textValue,barcodeType);
}2.css代码如下：.barcode {float:left;clear:both;padding: 0 10px; /*quiet zone*/overflow:auto;height:0.5in; /*size*/
}
.right { float:right; }
.barcode + * { clear:both; }
.barcode div {float:left;height: 0.35in; /*size*/
}
.barcode .bar1 { border-left:1px solid black; }
.barcode .bar2 { border-left:2px solid black; }
.barcode .bar3 { border-left:3px solid black; }
.barcode .bar4 { border-left:4px solid black; }
.barcode .space0 { margin-right:0 }
.barcode .space1 { margin-right:1px }
.barcode .space2 { margin-right:2px }
.barcode .space3 { margin-right:3px }
.barcode .space4 { margin-right:4px }
.barcode label {clear:both;display:block;text-align:center;font: 0.125in/100% helvetica; /*size*/
}
/*** bigger ******************************************/
.barcode2 {float:left;clear:both;padding: 0 10px; /*quiet zone*/overflow:auto;height:1in; /*size*/
}
.barcode2 + * { clear:both; }
.barcode2 div {float:left;height: 0.7in; /*size*/
}
.barcode2 .bar1 { border-left:2px solid black; }
.barcode2 .bar2 { border-left:4px solid black; }
.barcode2 .bar3 { border-left:6px solid black; }
.barcode2 .bar4 { border-left:8px solid black; }
.barcode2 .space0 { margin-right:0 }
.barcode2 .space1 { margin-right:2px }
.barcode2 .space2 { margin-right:4px }
.barcode2 .space3 { margin-right:6px }
.barcode2 .space4 { margin-right:8px }
.barcode2 label {clear:both;display:block;text-align:center;font: 0.250in/100% helvetica; /*size*/
