JavaScript解析错误 [英] JavaScript parse Error

问题描述

我正在使用laravel 5.1 PHP框架和来自javascript的符号图，但是当我从控制器发送数据时使用'(单引号)但JavaScript解析为一些未定义的值 $data_B_Temp = "{x : new Date('".$piecesTime[$dataLength]."'), y :".$pieces[$dataLength]."}";

I am using laravel 5.1 PHP framework and a sign chart from a javascript, But when i send data from controller with ' (single quote) but JavaScript Parse as some undefined value $data_B_Temp = "{x : new Date('".$piecesTime[$dataLength]."'), y :".$pieces[$dataLength]."}";

此变量将输入图形点

$(function () {

var chart = new CanvasJS.Chart("TempChart",
{


  axisX:{
    title: "time",
    gridThickness: 2,
    interval:1,
    intervalType: "hour",
    valueFormatString: "hh TT K",
    labelAngle: -10
  },
  axisY:{
    title: "distance"
  },
  data: [
  {
    type: "line",
   dataPoints:[{{$data_B_Temp }}]

  }
  ]
});

$("#TempChart").CanvasJSChart(chart.render());


});

但是javascript执行为:

But the javascript executes as :

dataPoints:[{x : new Date('2015-10-30 18:16:08'), y :38.5}]

我很困惑&#039即将来临?该怎么解决?

I'm confused &#039 is coming? how to solve it?

推荐答案

根据 Laravel刀片文档，使用{{ }}会导致转义的字符串，这将导致您看到的行为.

According to the Laravel Blade documentation, using {{ }} results in an escaped string, which would cause the behavior that you're seeing.

尝试使用{!! !!}代替；使用该语法将告诉Blade不要转义字符串.

Try using {!! !!} instead; using that syntax will tell Blade to not escape the string.

...
dataPoints: [{!! $data_B_Temp !!}]
...
