How to convert a json object into HTML format in java?
How to convert a json object into HTML in ja开发者_JS百科va?
There's no automatic way because a JSON object contains only data while in HTML there's markup semantics (there's no 1:1 mapping between JSON and HTML).
This code displays any Json object to HTML (using org.json lib):
/**
* Get the JSON data formated in HTML
*/
public String getHtmlData( String strJsonData ) {
return jsonToHtml( new JSONObject( strJsonData ) );
}
/**
* convert json Data to structured Html text
*
* @param json
* @return string
*/
private String jsonToHtml( Object obj ) {
StringBuilder html = new StringBuilder( );
try {
if (obj instanceof JSONObject) {
JSONObject jsonObject = (JSONObject)obj;
String[] keys = JSONObject.getNames( jsonObject );
html.append("<div class=\"json_object\">");
if (keys.length > 0) {
for (String key : keys) {
// print the key and open a DIV
html.append("<div><span class=\"json_key\">")
.append(key).append("</span> : ");
Object val = jsonObject.get(key);
// recursive call
html.append( jsonToHtml( val ) );
// close the div
html.append("</div>");
}
}
html.append("</div>");
} else if (obj instanceof JSONArray) {
JSONArray array = (JSONArray)obj;
for ( int i=0; i < array.length( ); i++) {
// recursive call
html.append( jsonToHtml( array.get(i) ) );
}
} else {
// print the value
html.append( obj );
}
} catch (JSONException e) { return e.getLocalizedMessage( ) ; }
return html.toString( );
}
then you just need to add specific CSS, like :
.json_object { margin:10px; padding-left:10px; border-left:1px solid #ccc}
.json_key { font-weight: bold; }
In trying to find an answer to your question, for myself, I came across this: Jemplate Not sure if that will help you. It did help me.
