How to display Google map for city

Image
By User



I am trying to display a Google map when a user searches for a city and presses the search button but I am not getting how to do it properly. Here is my code done so far. Not getting how to take user input and check that city is in array; if yes, then display it on Google map. For example, if user types city name Houston, USA then it should display on Google map after checking if city name is in our database.





Script:







function searchResult(cityname) { 

    var namesOfCity = ["houston,boston,newyork,florida"];



    //check the user input 



    //if match display it on google map    

}



function initialize() 

{

        if(GBrowserIsCompatible()) {

            var map = new GMap2(document.getElementById("map"));

            map.setCenter(new GLatLng(37.4419, -122.1419), 13);

            map.setUIToDefault();

        }

    }







HTML







<body onload="initialize()" onunload="GUnload()">





 <input type="text" id="cityname" value="" name=""/>

  <input id="search" type="button" value="Search" onclick="searchResult('cityname')" />

  <div id="map" style="width: 100%; height: 450px; position: relative; background-color: rgb(229, 227, 223);"></div>



</body>

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
