Grid- Find task based on Radio Button Selection

CraigLinn — Mon, 05 Jan 2015 21:00:17 GMT

I am looking for the best way to run a find task based on a radio button selection and export that to a grid. Thus I simply choose the correct radio button I want to use and search layer and populate results. Thanks,

Hi Craig,

You can do this by adding the findParams.layerIds to the doFind function. Ex:

function doFind() {
  if(registry.byId("radLayer1").checked){
    findParams.layerIds = [1];
  }
  else if(registry.byId("radLayer2").checked){
    findParams.layerIds = [4];
  }
  
  findParams.searchText = dom.byId("ownerName").value;
  findTask.execute(findParams, showResults);
}

Here is a JS Fiddle of a working example.

Thanks for your support! That does help. I should have been more detailed in my question. I have different rest services associated with each radio button. I would have a different table and search variable for each rest service. I was thinking about creating multiple find task with multiple table divs and with the radio button selected toggle all tables except that one, the same goes for search bar. What are your thoughts on that?

One way you could do this is use two different Grids in an accordion container. To use two different services, you will just need to place the FindTask within each function (i.e. in this example, findState and findCity).
