After I have operated on a list of checked items, how can I uncheck all the selected checkboxes?

Webix JS

Hi Everyone:
These aren’t working to uncheck all checkboxes:
$$(‘checkboxId’).attr(‘checked’,false);
$$(‘checkboxId’).setAttr(‘checked’,false);
What to do?

2

Is some page in documentation reffers to such API ?

All inputs have setValue, getValue api

$$("check").setValue(1); //or "on" if you are using custom check values

Using this http://webix.com/snippet/dbf0f202

I am getting: ‘Cannot read property of undefined’

All the following do not work:
$$(“checkbox”).setValue(0);
$$(“status”).setValue(0);
$$(“chk”).setValue(0);
$$(“webix_table_checkbox”).setValue(0);
$$(“input.webix_table_checkbox”).setValue(0);

How can I target all the checkboxes to set to 0?

You can’t change state of all checkboxes in the grid by one command. You will need to use eachRow operations

grid.eachRow(function(obj){ obj.checked =  "off"; })
grid.refresh();
6

grid.eachRow(function(obj){ alert(obj); obj.checked = “off”; })

The alert gives 1,2,3,4,5… which is the row id.
But alert(obj.checked) gives undefined … so do I targeted that checkbox to change checked?
I have tried alert(obj.checkbox), alert(obj.webix_table_checkbox) … resulting in undefined.

Sorry, was a my typo, the code must be like next

grid.eachRow(function(id){ this.getItem(id).checked = “off”; })

8

Unfortunately, no go…still getting undefined:
grid.eachRow(function(id){ console.log(this.getItem(id).checked); this.getItem(id).checked = “off”; })
