jQuery SyntaxError:意外令牌= [英] jQuery SyntaxError: Unexpected token =

问题描述

我试图将一堆变量传递给一个隐藏的输入值，但此代码中出现了一个愚蠢的语法错误:

I am trying to pass a bunch of variables to a hidden input value but I am getting a stupid syntax error in this code:

$('#imgdata').append(   
    '<input type="hidden" name="imgdata[' + id + '][width]" value="' + _width + '"/>
     <input type="hidden" name="imgdata[' + id + '][height]" value="' + _height + '"  />
     <input type="hidden" name="imgdata[' + id + '][left]" value="' + _left + '"  />
     <input type="hidden" name="imgdata[' + id + '][top]" value="' + _top + '"  />
     <input type="hidden" name="imgdata[' + id + '][src]" value="' + _src + '"  />'
 );

我必须忽略一个简单的语法错误.控制台在第三行告诉我.

I must be overlooking a simple syntax mistake. Console tells me its in 3rd line.

解决方案:

问题在于换行.使代码内联而不用按Enter键即可对其进行格式设置.

The issue was with the line-wrapping. Making the code inline without pressing enter for formatting fixed it.

推荐答案

JavaScript字符串行必须以\结尾. 除此之外，请确保所有变量均已定义.

JavaScript string lines must be end with \. Besides that make sure all the variables are indeed defined.

您的代码示例应如下:

$('#imgdata').append(   
    '<input type="hidden" name="imgdata[' + id + '][width]" value="' + _width + '"/>\
     <input type="hidden" name="imgdata[' + id + '][height]" value="' + _height + '"  />\
     <input type="hidden" name="imgdata[' + id + '][left]" value="' + _left + '"  />\
     <input type="hidden" name="imgdata[' + id + '][top]" value="' + _top + '"  />\
     <input type="hidden" name="imgdata[' + id + '][src]" value="' + _src + '"  />'
 );​
