jQuery查找具有特定值的所有元素

Question

When a user clicks on my radio button:

<input type="radio" name="allselect" onClick="javascript: _select('none');" />

I need the function _select(param) to find every radio button with a value of param, so 'none' in this case, and click it. How can this be done in jquery?

Answer 1

Since you are using jQuery:

<input type="radio" name="allselect" id="selectnone" />

JS:

$('#selectnone').click(function(){
    $('input[type=checkbox]').each(function(){
          if(this.value === 'none') this.checked = true;
    });
});

Answer 2

I'd think that the following, as yet untested approach, would work:

$('input:radio').click(
    function(){
        var inputsOfValueEqualToNone = $('input:radio[value="none"]');
    });

Making the above into a more function-based approach:

function _select(param){
    if (!param){
        return false;
    }
    else {
        inputs = $('input:radio[value="' + param + '"]').click();
    }
}

References:

• :radio selector .
• attribute-equals ( [attribute="value"] ) selector .

Answer 3

Try this

function _select(param){
   var rBtns = $('input[name=' + param + ']');
   rBtns.click();//Calling the click method on all the radio buttons it found
}

Answer 4

You can do this:

function _select(paramVal){
   $('input[value=' +paramVal +']').trigger('click');
}

Answer 5

Use:

function _select( value ) {
  var elems $('input:radio[value='+value+']'); // all the radio buttons with the value
}
