        'var doughnutData = [' +
        '{' +
        ' value: percentage,' +
//not work with this variable but with a number like 50 it work
        ' color:"#68dff0"' +``
        '},' +
        '{' +
        'value : remain,' +
//not work with this variable but with a number like 50 it work
        'color : "#444c57"' +
        '}' +
        ' ];' +
        'var myDoughnut = new Chart(document.getElementById("serverstatus0' + i + '").getContext("2d")).Doughnut(x);' +

百分比是变量吗？

如果是这样的话，那就是：

＆＃39; +

    'var doughnutData = [' +
    '{' +
    ' value: ' + percentage + ',' +
    ' color:"#68dff0"' +``
    '},' +
    '{' +
    'value : '+ remain + ',' +
    'color : "#444c57"' +
    '}' +
    ' ];' +
    'var myDoughnut = new Chart(document.getElementById("serverstatus0' + i + '").getContext("2d")).Doughnut(x);' +
    ' </script>' +

看看我如何将剩余和百分比文本更改为不在引号中？
