jQuery enabling/disabling checkbox

jsFiddle: http://jsfiddle.net/KUcrm/

I have this code:

HTML

<input id="Check1" type="checkbox" name="ckbRG" tabindex="1" checked /><label for="Check1"> Check1</label><br />
<input name="txt1" type="text" maxlength="10" id="txt1" tabindex="2" />
<br /><br /><br />
<input id="Check2" type="checkbox" name="ckbNome" tabindex="3" checked /><label for="Check2"> Check2</label><br />
<input name="txt2" type="text" maxlength="10" id="txt2" tabindex="2" />

jQuery

$("#Check1").click(function() {
    if ($("#Check1").attr("checked")) {
        $("#txt1").removeAttr("disabled");
    } else {
        $("#txt1").attr("disabled", "disa开发者_JAVA百科bled");
    }
});


$("#Check2").click(function() {
     if ($("#Check2").attr("checked")) {
         $("#txt2").removeAttr("disabled");
     } else {
         $("#txt2").attr("disabled", "disabled");
     }
    $("#Check1").click();
});

By selecting Check2, Check1 should also be selected but apparently the click event on Ckeck1 runs before the Check1 changes state (marked/unmarked). Then when the Check1 is checked txt1 is off and when not selected the txt1 is on.

You should be using .change instead of click. It will trigger when the checkbox changes.

I think you want:

$("#Check1").click().triggerHandler('click');
