Answer 4

<script >
function getArgs(strParame) {
         var args = new Object();
         var query = location.search.substring(1); // Get query string
         var pairs = query.split("&"); // Break at ampersand
         for (var i = 0; i < pairs.length; i++) {
             var pos = pairs[i].indexOf('='); // Look for "name=value"
             if (pos == -1) continue; // If not found, skip
             var argname = pairs[i].substring(0, pos); // Extract the name
             var value = pairs[i].substring(pos + 1); // Extract the value
             value = decodeURIComponent(value); // Decode it, if needed
             args[argname] = value; // Store as a property
         }
         return args[strParame]; // Return the object
     }
console.log(getArgs("参数名"));
</script >

Answer 5

xhr当中有个getResponseHeader

var client = new XMLHttpRequest();
client.open("GET", "unicorns-are-teh-awesome.txt", true);
client.send();
client.onreadystatechange = function() {
  if(this.readyState == this.HEADERS_RECEIVED) {
    console.log(client.getResponseHeader("Content-Type"));
  }
}
