Question

我正在尝试在vb.net中使用highchart。当我启动 ScriptManager.RegisterClientScriptBlock chrome返回 未捕获的SyntaxError：意外的令牌ILLEGAL

VB代码：

    Dim Script As String
    Script = "$(function () {\n"
    Script += "$('#container').highcharts({\n"
    Script += "chart: {\n"
    Script += "type: 'line'\n"
    Script += "},\n"
    Script += "title: {\n"
    Script += "text: 'Consumos por semanas'\n"
    Script += "},\n"
    Script += "subtitle: {\n"
    Script += "text: 'Kwh/Módulos-Piezas'\n"
    Script += "},\n"
    Script += "xAxis: {\n"
    Script += "categories: ['25', '26']\n"
    Script += "},\n"
    Script += "yAxis: {\n"
    Script += "title: {\n"
    Script += "text: 'Kwh'\n"
    Script += "}\n"
    Script += "},\n"
    Script += "plotOptions: {\n"
    Script += "line: {\n"
    Script += "dataLabels: {\n"
    Script += "enabled: true\n"
    Script += "},\n"
    Script += "enableMouseTracking: false\n"
    Script += "}\n"
    Script += "},\n"
    Script += "series: [{\n"
    Script += "name: 'cach',\n"
    Script += "data: [1.1003, 6.5265]},\n"
    Script += "]\n"
    Script += "});\n"
    Script += "});"

    Dim popupScript = "<script type='text/javascript'>" + Script + "</script>"
    ScriptManager.RegisterClientScriptBlock(Me, Me.GetType(), "onload", popupScript, False)

aspx代码：

<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<script src="../../scripts/jquery-1.6.4.min.js" type="text/javascript"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

如果我将脚本变量导出到txt文件并将\ n替换为换行符并将代码放在hightchart demo code中，则可以正常工作。如果我将代码直接粘贴到函数javascript中的aspx文件中，它就可以工作。

任何想法??

问题是' \ n '不是在VB字符串中定义新行的正确方法。那可能适用于C＃，但不适用于VB.NET。您想使用vbCrLf常量。

此外，如果可以在一个语句中定义，则不应使用重复的连接来构建字符串。

  Dim Script As String = "$(function () {" & vbCrLf &
       "$('#container').highcharts({" & vbCrLf &
       "chart: {" & vbCrLf &
       "type: 'line'" & vbCrLf &
       "}," & vbCrLf &
       "title: {" & vbCrLf &
       "text: 'Consumos por semanas'" & vbCrLf &
       "}," & vbCrLf &
       "subtitle: {" & vbCrLf &
       "text: 'Kwh/Módulos-Piezas'" & vbCrLf &
       "}," & vbCrLf &
       "xAxis: {" & vbCrLf &
       "categories: ['25', '26']" & vbCrLf &
       "}," & vbCrLf &
       "yAxis: {" & vbCrLf &
       "title: {" & vbCrLf &
       "text: 'Kwh'" & vbCrLf &
       "}" & vbCrLf &
       "}," & vbCrLf &
       "plotOptions: {" & vbCrLf &
       "line: {" & vbCrLf &
       "dataLabels: {" & vbCrLf &
       "enabled: true" & vbCrLf &
       "}," & vbCrLf &
       "enableMouseTracking: false" & vbCrLf &
       "}" & vbCrLf &
       "}," & vbCrLf &
       "series: [{" & vbCrLf &
       "name: 'cach'," & vbCrLf &
       "data: [1.1003, 6.5265]}," & vbCrLf &
       "]" & vbCrLf &
       "});" & vbCrLf &
       "});"

带有highcharts的意外标记ILLEGAL
