    <p>Good Day,</p> <p>I am a newbie learning Javascript &amp; Dojo and I typically learn by picking apart other parts of running code.</p> <p>I am confused as to how to get a substring value from the following code (from the <a href="http://developers.arcgis.com/en/javascript/sandbox/sandbox.html?sample=query_nomap" rel="nofollow">ArcGIS Sandbox</a>):</p> <pre><code> &lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt; &lt;meta http-equiv="X-UA-Compatible" content="IE=7, IE=9, IE=10"&gt; &lt;!--The viewport meta tag is used to improve the presentation and behavior of the samples on iOS devices--&gt; &lt;meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"&gt; &lt;title&gt;Query State Info without Map&lt;/title&gt; &lt;script src="http://js.arcgis.com/3.6/"&gt;&lt;/script&gt; &lt;script&gt; dojo.require("esri.tasks.query"); dojo.require("esri.map"); var queryTask, query; require([ "esri/tasks/query", "esri/tasks/QueryTask", "dojo/dom", "dojo/on", "dojo/domReady!" ], function( Query, QueryTask, dom, on ){ queryTask = new QueryTask("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/5"); query = new Query(); query.returnGeometry = false; query.outFields = ["SQMI","STATE_NAME","STATE_FIPS","SUB_REGION","STATE_ABBR","POP2000","POP2007","POP00_SQMI","POP07_SQMI","HOUSEHOLDS","MALES","FEMALES","WHITE","BLACK","AMERI_ES","ASIAN","OTHER","HISPANIC","AGE_UNDER5","AGE_5_17","AGE_18_21","AGE_22_29","AGE_30_39","AGE_40_49","AGE_50_64","AGE_65_UP"]; on(dom.byId("execute"), "click", execute); function execute(stateName) { query.text = dom.byId("stateName").value; //execute query queryTask.execute(query, showResults); } function showResults(results) { var s = ""; for (var i=0, il=results.features.length; i&lt;il; i++) { var featureAttributes = results.features[i].attributes; for (att in featureAttributes) { s = s + "&lt;b&gt;" + att + ":&lt;/b&gt; " + featureAttributes[att] + "&lt;br&gt;"; } s = s + "&lt;br&gt;"; } dom.byId("info").innerHTML = s; } }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; US state name : &lt;input type="text" id="stateName" value="California"&gt; &lt;input id="execute" type="button" value="Get Details"&gt; &lt;br /&gt; &lt;br /&gt; &lt;div id="info" style="padding:5px; margin:5px; background-color:#eee;"&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>All I would like to do is pick apart the input (in this case the id="stateName" which is the word California). </p> <p>So a silly example would be substituting the following code to get the first 10 characters of when someone types in 'California is on the west coast'</p> <pre><code> query.text = dom.byId("stateName").substring(0,10); </code></pre> <p>This is really so I can support other queries but I figured if I can do a substring on this input then it is really the same anytime when I query other attributes.</p> <p>Thanks in advance for a newbie !</p>

    1. COFrom `query.text = dom.byId("stateName").substring(0,10);` it seems you know how to do what you asked... you need to rephrase your question if you are unclear on something.

    2. COHi Wyatt, well I thought I knew something but when I used that substitution it does not work. I must be doing something wrong.

    3. COI commented on the answer below because the answer is so close. It should be `query.text = dom.byId("stateName").value.substring(0, 10);`. I've edited @DesertIvy's answer but it still needs to be peer-reviewed and accepted.

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
