Facility Control

Hello,

I have an String key/value constraint , and i want to add new values to it. So, i need to read all existing key/value pairs, and add to the new one. But i lost in how to read the values - i only have succeed with names (using getChoices), and i can read the selected value - but not all values.. 

How to achieve that? 

Thank you!

Hi alex, 

You can get all the values you need in a for loop and use the getValues() API of single constraint. I will post an example below for you to refer.

            <constraint key="1">one</constraint>

            <constraint key="2">two</constraint>

            <constraint key="3">three</constraint>

            <constraint key="5">five</constraint>

            <constraint key="8">eight</constraint>

            <constraint key="13">thirteen</constraint>

            <constraint key="21">twentyone</constraint>

         </param>

      </params>

var choices = numList.getChoices();

var output = "Constraints are:";

for (var i = 0; i &lt; choices.length; i++) {

   output = output + "\nitem " + choices[i].getValue() + " = " + choices[i].getName();   

}

ogscript.rename("output", output);</task>

   </button>

Hello Eric and thank you for the answer
Your code is good for constrainttype="INT_CHOICE" yype of parameter. In my case, i use constrainttype="STRING_STRING_CHOICE" type, so the getValues() doesn't work for that one..

Hi alex

I recommend using getValue() instead of getValues() for single choice, and then you can using a for loop to get the values. 

The code below is based on your code about how to get the IP and camera names.

<abs contexttype="opengear" gridsize="20" id="_top" keepalive="false">
<meta>
<params>
<param access="1" constraintstrict="false" constrainttype="STRING_STRING_CHOICE" maxlength="0" name="IP" oid="IP" type="STRING" value="192.168.2.45" widget="radio-toggle">
<constraint key="192.168.2.43">Camera-1</constraint>
<constraint key="192.168.2.45">Camera-2</constraint>
</param>
<param access="1" maxlength="0" name="newIp" oid="newIp" type="STRING" value="" widget="default"/>
<param access="1" maxlength="0" name="newName" oid="newName" type="STRING" value="" widget="default"/>
</params>
</meta>
<param expand="true" height="40" left="60" oid="IP" style="t:style:navigationButton;f:style:navigationButton;" top="40" width="920">
<task tasktype="ogscript">ogscript.debug(this.getValue());

var strList = params.getConstraint("IP");

var choices = strList.getChoices();

var output = "Constraints are:";

for (var i = 0; i &lt; choices.length; i++)
{
output = output + "\nitem " + choices[i].getValue() + " = " + choices[i].getName();
ogscript.debug(output)
}</task>
</param>
<abs height="60" left="60" top="100" width="360">
<label height="20" left="0" name="Add/Delete to parameter constrain:" style="txt-align:center;size:Big;" top="0" width="320"/>
<param expand="true" height="20" left="220" oid="newIp" top="40" width="120"/>

Thanks, i did the same but without succeess.. i guess i missed something. Will check it tommorow. Thank you very much!

Ok, i just checked that code - and its doesnt working. I got in debug:
item 0 = Camera-1
item 0 = Camera-2

(i did the same and  got the same results before posting that post)

While i expect to get:

192.168.2.43= Camera-1
192.168.2.45 = Camera-2

Did you checked your code and got that values? I'm running the last 9.02 version of dashboard. 

Hi Alex,

You can get that value by changing

choices[i].getValue() to choices[i].getValueString()

Hello, Eric, thank you, choices[i].getValueString() is work!
