Add the value obtained by js to the array and upload it to the PHP file. what is the result? (Online, etc.) js code: functionqueren () {& nbsp; vararrnewArray (); & nbsp; varcheckboxdocument. getElementsByName (& quot; name & quot;); & nbsp; for (vari0; I & lt. js puts the obtained values into an array and uploads them to the PHP file? (Online)
Js code:
Function queren (){
Var arr = new Array ();
Var checkbox = document. getElementsByName ("name ");
For (var I = 0; I If (checkbox [I]. checked = true ){
Arr [I] = checkbox [I]. value;
}
}
}

1. AJAX is used to return the data type in json
2. return a string using AJAX, in the form of str1, str2, str3. PHP receives the string and then uses explode to process it as an array.
