Question

document.write("<img style=\"width:0px;height:0px\" src=\"http:\/\/127.0.0.1\/51la.asp?id='+window.location.search+'\" \/>");window.location.search为什么没获取到值？怎么写能获取到？

Answer 1

document.write("<img style=\"width:0px;height:0px\" src=\"http:\/\/127.0.0.1\/51la.asp?id='"+window.location.search+"'\" \/>");

Answer 2

好像不要单引号。因为你最外面是双引号，所以+号前后也要是双引号。
document.write("<img style=\"width:0px;height:0px\" src=\"http:\/\/127.0.0.1\/51la.asp?id="+window.location.search+"\" \/>");
