<table>表數(shù)據(jù)轉 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是你要轉化的表的表名，是一個字符串，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 += "\""; //加上一個雙引號

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>
