Below is one simple function that saves my required json in localstorage using JavaScript array.


function saveMyJson(key,value)
{

// initialise array
var myObj = {};

// get existing json from local storage
if(localStorage.getItem('my_json') != null)
myObj = JSON.parse(localStorage.getItem('my_json'));

// add element in json by key-value pair
eval("myObj['" + key + "'] = \""+ value + "\"; ");

// set updated json in local storage
localStorage.setItem('my_json', JSON.stringify(myObj));

}

Add this code in ckeditor/config.js.
Which will convert style property height, width and float to height=””, width=”” and align=””.

CKEDITOR.on('instanceReady', function (ev) {		
									  
// Ends self closing tags the HTML4 way, like <br>.
ev.editor.dataProcessor.htmlFilter.addRules(
    {
        elements:
        {
            $: function (element) {
                // Output dimensions of images as width and height
                if (element.name == 'img') {
                    var style = element.attributes.style;

                    if (style) {
                        // Get the width from the style.
                        var match = /(?:^|\s)width\s*:\s*(\d+)px/i.exec(style),
                        width = match && match[1];

                        // Get the height from the style.
                        match = /(?:^|\s)height\s*:\s*(\d+)px/i.exec(style);
                        var height = match && match[1];
						
						// Get the float from the style.
                        match = /(?:^|\s)float\s*:\s*(\w+)/i.exec(style);
                        var float = match && match[1];
						
                        if (width) {
                            element.attributes.style = element.attributes.style.replace(/(?:^|\s)width\s*:\s*(\d+)px;?/i, '');
                            element.attributes.width = width;
                        }

                        if (height) {

                            element.attributes.height = height;
                        }
						 if (float) {
                            element.attributes.style = element.attributes.style.replace(/(?:^|\s)float\s*:\s*(\w+)/i, '');
                            element.attributes.align = float;
                        }
						
                    }
                }



                if (!element.attributes.style)
                    delete element.attributes.style;
