Does it really have two input elements with the same name?

Question

i.e:.

<form 1> <input type="hidden" name="url" value="1"> </form 1> 

and

 <form 2> <input type="hidden" name="url" value="2"> </form 2> 

Is this permissible and permissible?

Answer 1

Yes, in your case, it really is. Consider this:

It's good

 <form name="form1"> <input type="hidden" name="url" value="1"> </form> <form name="form2"> <input type="hidden" name="url" value="2"> </form> 

This is not good

 <form name="form1"> <input type="hidden" name="url" value="1"> <input type="hidden" name="url" value="2"> </form> 

Answer 2

Yes.

It is also important if you are dealing with switch groups.

Answer 3

Yes - everyone will send only their forms.

If you have them in the same form, one will override the other, and it is invalid.

Answer 4

"This is not good" correctly analyzes all browsers that I know of; if two urls appear in the url encoded string, they will be treated as an array. Try this in jQuery:

 $('<form name="form1">\ <input type="hidden" name="url" value="1">\ <input type="hidden" name="url" value="2">\ </form>').serialize() 

and you will get: "url=1&url=2"

A well-written query parser will return a json structure as follows:

  {"url":["1", "2"]} 

Is this a strictly specification? No, but not one of them creates a multi-line string, avoiding the backslash EOL, as I said above.

Answer 5

To check if this is true or not, create a page and test it on the W3C here:

Answer 6

 A) < form 1> < input type="hidden" name="url" value="1"> < /form 1> and < form 2> < input type="hidden" name="url" value="2"> < /form 2> is Okay,beacuse forms submiting time will be different B) < form 1> < input type="hidden" name="url" value="1"> < input type="hidden" name="url" value="2"> < /form 1> is also okay, but not standard coding practice JAVA Code two extract both values :: Map<String,String[]> parmMap = requestObj.getParameterMap(); String input1 = parmMap.get("url")[0]; String input2 = parmMap.get("url")[1];
