JavaScript is not working as expected.

#JavaScript #ObjectScript #Other

I have the following method call (have included html and css as well). when I debug the code in a browser, JavaScript seems to work fine. Loading image is coming up, table is getting hidden. But when I close the debug and just load the page and run it, loading image is not coming up, neither the table is hidden. Not sure what is going on? I need help to understand what I am doing wrong?

XData Style

{

<style type="text/css">

#loading {width: 100%;height: 100%;top: 0px;left: 0px;position: fixed;display: block; z-index: 99}

#loading-image {position: absolute;top: 40%;left: 45%;z-index: 100}

</style>

}

 

XData Contents [ XMLNamespace = "http://www.intersystems.com/zen" ]

{

<page xmlns="http://www.intersystems.com/zen">

<html>

<div id="loading" style="display:none;">

<img id="loading-image" src="../progressindicator.gif"  alt="Loading..." />

</div>  

<h1 containerStyle="">Testing </h1>

</html>

<spacer height="20" />

<button onclick="zenPage.displayData()" containerStyle="padding:10px; margin-left:10px;font-size:16px;" caption="Run Test" />

<spacer height="20" />

<tablePane id="tblResults" valueColumn="ID"

tableName="UnitTest.tblMessageTypeResults"

orderByClause = "ID asc"

 hidden="true" >

<column colName="ID" hidden="true" />

<column colName="MessageName" />

<column colName="MessageCode" />

<column colName="TestStatus"  />

<condition colName="TestStatus"

                predicate="STARTSWITH"

                value="Fail"

                    rowStyle="color: red;"/>

</tablePane>

</page>

}

ClientMethod displayData() [ Language = javascript ]

{

    //show the loader first

    document.getElementById("loading").style.display = "block"

    //alert("Please note that it will take 5-10 to run these tests.");

    // wait for the function to respond with the message before proceeding further

    zenSynchronousMode = 1;  

    var table = zenPage.getComponentById('tblResults');

    // show the table - as initially it is hidden.

    table.setProperty("hidden",true);

    // call the method to run all the test and wait for it finish

    var getResults = zenPage.CallRunTestMethod();

    //var getResults = "";

    if (getResults == ""){

        // alerts works but loading image does not

        alert("Test Run completed!");

        table.setProperty("hidden",false)

        // execute the query and show the results

        table.executeQuery();

        zenSynchronousMode = 0; //returns to the original value

        // hide the loader.

        document.getElementById("loading").style.display = "none"      

    }

    else {

        // show alert with error message

        alert("Test Failed: error returned " + getResults + ". Please click on run test button again to repeat test.");

        var table = zenPage.getComponentById('tblResults');

        //hide the table - not sure if there is any other option

        table.setProperty("hidden",true)

        // hide the loader

        document.getElementById("loading").style.display = "none"

    }

}

 

}

Ok- tried it and still no luck. I have changed the code so It is doing the following and now it seems to work. ClientMethod displayResults() [ Language = javascript ] { document.getElementById("loading").style.display = "block"; // show loader image zenPage.getComponentById('tblResults').setHidden(true); // hide the table setTimeout(function(){zenPage.displayData();}, 1000); // run test and populate table in a second } ClientMethod displayData() [ Language = javascript ] { // wait for the function to respond with the message before proceeding further zenSynchronousMode = 1; var getResults = zenPage.CallRunTestMethod();// call the method to run test if (getResults == ""){ var table = zenPage.getComponentById('tblResults'); table.setHidden(false); table.executeQuery();// execute the query and show the results zenSynchronousMode = 0; document.getElementById("loading").style.display = "none"; // hide the loader. } else { alert("Test Failed: error returned " + getResults + ". Please click on run test button again to repeat test."); zenPage.getComponentById('tblResults').setHidden(true); // hide the table document.getElementById("loading").style.display = "none"; // hide the loader } } }
