javascript - 设置为带有大量 ""的变量文本

Question

我试图将其设置为变量:

<svg width="500" height="400" xmlns="http://www.w3.org/2000/svg">  <!-- Created with Method Draw - http://github.com/duopixel/Method-Draw/ -->  <g>   <title>background</title>   <rect fill="#fff" id="canvas_background" height="402" width="502" y="-1" x="-1"/>   <g display="none" overflow="visible" y="0" x="0" height="100%" width="100%" id="canvasGrid">    <rect fill="url(#gridpattern)" stroke-width="0" y="0" x="0" height="100%" width="100%"/>   </g>  </g>  <g>   <title>Layer 1</title>   <ellipse ry="69" rx="75" id="svg_1" cy="172" cx="207" fill-opacity="0.7" stroke-width="2" stroke="#995757" fill="#FF8787"/>  </g> </svg>

问题是我想将其作为文本存储在变量中，但起始的“”从文本本身的“”中关闭。

我该如何正确设置？

e.g: var svgSource = "<svg width="500" height="400" xmlns="http://www.w3.org/2000/svg">
 <!-- Created with Method Draw - http://github.com/duopixel/Method-Draw/ -->
 <g>
  <title>background</title>
  <rect fill="#fff" id="canvas_background" height="402" width="502" y="-1" x="-1"/>
  <g display="none" overflow="visible" y="0" x="0" height="100%" width="100%" id="canvasGrid">
   <rect fill="url(#gridpattern)" stroke-width="0" y="0" x="0" height="100%" width="100%"/>
  </g>
 </g>
 <g>
  <title>Layer 1</title>
  <ellipse ry="69" rx="75" id="svg_1" cy="172" cx="207" fill-opacity="0.7" stroke-width="2" stroke="#995757" fill="#FF8787"/>
 </g>
</svg>"

Answer 1

使用单引号。

var svgSource = '<svg width="500" height="400" xmlns="http://www.w3.org/2000/svg">  <!-- Created with Method Draw - http://github.com/duopixel/Method-Draw/ -->  <g>   <title>background</title>   <rect fill="#fff" id="canvas_background" height="402" width="502" y="-1" x="-1"/>   <g display="none" overflow="visible" y="0" x="0" height="100%" width="100%" id="canvasGrid">    <rect fill="url(#gridpattern)" stroke-width="0" y="0" x="0" height="100%" width="100%"/>   </g>  </g>  <g>   <title>Layer 1</title>   <ellipse ry="69" rx="75" id="svg_1" cy="172" cx="207" fill-opacity="0.7" stroke-width="2" stroke="#995757" fill="#FF8787"/>  </g> </svg>'

我仔细查看了它 - 你的整个字符串没有一个单引号，只有双引号。因此只需使用单引号将其括起来即可正常工作。
