ip与int互转，html互转js

function ipToint(ip){
    if(!ip || ip.length==0){return;}
    var ip = ip.split(".");
    ip = Number(ip[0]) * 256 * 256 * 256 + Number(ip[1]) * 256 * 256 + Number(ip[2]) * 256 + Number(ip[3]);
    ip = ip >>> 0;
    return ip;
}

function intToip(str){
    var arr = new Array();
    arr[0] = (str >>> 24) >>> 0;
    arr[1] = ((str << 8) >>> 24) >>> 0;
    arr[2] = (str << 16) >>> 24;
    arr[3] = (str << 24) >>> 24;
    return String(arr[0]) + "." + String(arr[1]) + "." + String(arr[2]) + "." + String(arr[3]);
}

function html2js(text){
    var split1 = text.split("\n");
    text = "var text = \"\";\n";
    for(var i=0;i<split1.length;i++) {
        var str = split1[i];
        text += "text += \""+str.replace(/"/g,"\\\"")+"\";\n";
    }
    return text;
}

function js2html(text){
    var txt = eval（"("+text+")");
    return txt;
}
