Select options value and text to JSON format

Answer 1

I'm not exactly sure what you mean. Do you mean you want something like this?

{ select : [ {option: {value:1, text:"First"}},
             {option: {value:2, text:"Second"}},
             {option: {value:3, text:"Third"}},
             {option: {value:4, text:"Fourth"}}
           ]
}

You can parse and stringify any object in Javascript with this. First you need to build up your object. You can do something like this:

var selectJson = {};
selectJson.select = new Array();
var select = document.getElementById("mySelectId");

for(var i = 0; i < select.options.length; i++) {
   var option = select.options[i];
   var optionJson = {};
   optionJson.option = {value: option.value, text: option.text};
   selectJson.select.push(optionJson);
}

Then use the stringifier to convert it into a JSON string.
