JS中将[["123","456","789"],[["123","456","789"],[["123","456","789"],[["123","456","789"]...] 格式的转换成二维数组

function jsonToArr(jsonData) {
    var jsonsString = jsonData.slice(1, jsonData.length - 1);
    var jsonStrings = jsonsString.split("],")
    var length = jsonStrings.length;
    for (var i = 0; i < length-1; i++) {
        jsonStrings[i] += ']';
    }
    var source = [[length]];
    for (var j = 0; j < length; ++j) {
        var oneObj = jsonStrings[j].replace(/"/g,'')
                        .replace('[','')
                        .replace(']','')
                        .split(",");
        source.push(oneObj);
    }
    return source;
}

JS中替换和分割方法的使用。

jsonStrings.replace(/"/g,'')
.replace('[','')
.replace(']','')
