will be a string (can be Chinese, in the generation of two-dimensional code image before the Chinese transcoding code to generate two-dimensional code picture, if you want to take a log of two-dimensional code, you can create a two-dimensional code in the middle part of their own add a small log,log picture not too large, otherwise it will not scan out the content.
Copy Code code as follows:
<title></title>
<script src= "Js/jquery-1.8.3.js" type= "Text/javascript" ></script>
<script src= "Js/qrcode.js" type= "Text/javascript" ></script>

<script type= "Text/javascript" >
$ (function () {
$ ("#bt"). Bind ("click", Function () {
Text = $ ("#text"). Val ();
$ ("#div_div"). QRCode (Utf16to8 (text));
})
})
function Utf16to8 (str) {//transcoding
var out, I, Len, C;
out = "";
len = str.length;
for (i = 0; i < len; i++) {
c = str.charcodeat (i);
if ((c >= 0x0001) && (c <= 0x007f)) {
Out + + Str.charat (i);
else if (C > 0x07ff) {
Out + + string.fromcharcode (0xe0 | ((c >>) & 0x0f));

Here quoted three JS package, one is jquery package, this casual version, the other two is to draw two-dimensional code with the JS package.

PS: Here again to provide a site of the two-dimensional Code generation tool enhanced version (with logos and a variety of custom functions) for everyone to use:
