I am trying to pass a bunch of variables to a hidden input value

  • 0

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 + '"  />'
 );

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

SOLUTION:

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

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

    You code sample should be as follows:

    $('#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 + '"  />'
 );​
