php - Dealing with an array of input text dynamically generated in JavaScript -

-

i want phone numbers of customer in form generates input text dynamically. have made this

<html> <head> <title> telephones </title>  <script language="javascript"> function add(type) {  //create input text dynamically.      if(typeof add.counter=='undefined')     {         add.counter=0;     }     add.counter++;     var element = document.createelement("input");      //assign different attributes element.     element.setattribute("type", type);     element.setattribute("value", "");     element.setattribute("name", type.concat(add.counter));      var foo = document.getelementbyid("foobar");      //append element in page (in span).     foo.appendchild(element);     return add.counter;    } </script> </head> <body> <form action="test1.php" method="post">  //here think there problem <input type="button" value="add" onclick="<?php echo "add('text')";?>"/> <input type="submit" value="add" /> <span id="foobar">&nbsp;</span>  </form> </body> </html>

i want array of names of input text, or last value of counter

if set input name "whatever[]" php automatically create array input data need here change

element.setattribute("name", type.concat(add.counter)); // element.setattribute("name", "thename[]");

and don't want reuse type of elements it's name - that's 2 different things, come better

and drop counter stuff

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
