Javascript detect Chinese Character

Here is the function to detect Chinese Chracters. However, we need do more research about CJK (Chinese, Japanese, Korean) about the unicode character range.

function isChineseCharacter(str) {

    var re1 = new RegExp("^[\u4E00-\uFA29]*$"); //Chinese character range
    var re2 = new RegExp("^[\uE7C7-\uE7F3]*$"); //non Chinese character range
    str = str.replace(/\s/g, '');

    if (!re1.test(str) || re2.test(str)) {
        console.log("Oops, Please input Chinese character.");
        return false;
    }

    console.log('Chinese character');
    return true;
}

Chrome throws SecurityException when access sessonStorage or localStorage

chrome://settings/content


Under Settings > Privacy > Content settings, change the cookies' settings to "Allow local data to be set" or the second option. Also don't check "Block third-party cookies and site data".


When the option checked, Iframe in Chrome will throw error: Uncaught SecurityError: Failed to read the 'sessionStorage' property from 'Window'.

My understanding is: site data can be sessionStorage or localStorage. Suggest Chrome changes the section title from "Cookies" to "Cookies and site data".:-)


When "Block third-party cookies and site data" is checked, iframe site will be considered third-party.
