html table表數(shù)據(jù)轉(zhuǎn)Json格式示例代碼

    <table>表數(shù)據(jù)轉(zhuǎn) Json 格式的javascript函數(shù)如下
    代碼如下:
    <script>
    var keysArr = new Array("key0", "key1","key2");
    function TableToJson(tableid) { //tableid是你要轉(zhuǎn)化的表的表名，是一個(gè)字符串，如"example"
    var rows = document.getElementById(tableid).rows.length; //獲得行數(shù)(包括thead)
    var colums = document.getElementById(tableid).rows[0].cells.length; //獲得列數(shù)
    var json = "[";
    var tdValue;
    for (var i = 1; i < rows; i++) { //每行
    json += "{";
    for (var j = 0; j < colums; j++) {
    tdName = keysArr[j]; //Json數(shù)據(jù)的鍵
    json += "\""; //加上一個(gè)雙引號(hào)
    json += tdName;
    json += "\"";
    json += ":";
    tdValue = document.getElementById(tableid).rows[i].cells[j].innerHTML;//Json數(shù)據(jù)的值
    if (j === 1) {//第1列是日期格式，需要按照json要求做如下添加
    tdValue = "\/Date(" + tdValue + ")\/";
    }
    json += "\"";
    json += tdValue;
    json += "\"";
    json += ",";
    }
    json = json.substring(0, json.length - 1);
    json += "}";
    json += ",";
    }
    json = json.substring(0, json.length - 1);
    json += "]";
    return json;
    }
    </script>
