Make the checkbox unselected and the checkbox unselected

Make the checkbox unselected and the checkbox unselected

Today, when I was working on a project, I encountered a problem. You need to leave the selected checkbox empty so that the selected checkbox will not be selected. Finally, we will record a method that is very useful.

$ ("Input [type = 'checkbox']"). each (function (){
If (this. checked ){
This. checked = false;
}
});

Principle: loop every input whose type is checkbox. If it is selected, it is OK to set its checked attribute to false.

Of course, if you want to implement the reselect effect, just add a bit more. The Code is as follows:

$ ("Input [type = 'checkbox']"). each (function (){
If (this. checked ){
This. checked = false;
}

If (! (This. checked )){
This. checked = true;
}
});

 

In the groupbox of the winform program, how does one make all the checkboxes unselected? (One selected by default)

Foreach (RadioButton r in groupBox1.Controls)
{
R. AutoCheck = false; // disable automatic selection !!!!!
R. Checked = false; // all are not selected
}

How can I disable multiple checkboxes from being selected?

Set the name attribute of all the checkboxes you want to control to the same name.
Write the following code in js:
Var boxes = document. getElementByName ('A ');

For (var I = 0; I <boxes. length; I ++)
{
Boxes [I]. checked = false
}
