自定义复选框在Chrome和Safari浏览器中无法使用 [英] Custom checkbox not working in Chrome and Safari browser

问题描述

我使用下面的代码自定义复选框，

HTML

 < div class =agree> 
< label for =agree_checkclass =label_check>< input type =checkboxclass =agree_checkid =agree_check/> Agree< / label& 
< / div> 
  

CSS

  .has-js .label_check {padding-left：34px; } 
 .has-js .label_check {background：url（../ images / box1.png）no-repeat; } 
 .has-js label.c_on {background：url（../ images / box1-with-mark.png）no-repeat; } 
 .has-js .label_check input {position：absolute; left：-9999px; } 
  

脚本

 < script type =text / javascript> 
 var d = document; 
 var safari =（navigator.userAgent.toLowerCase（）。indexOf（'safari'）！= -1）？真假; 
 var gebtn = function（parEl，child）{return parEl.getElementsByTagName（child）; }; 
 onload = function（）{
 
 var body = gebtn（d，'body'）[0]; 
 body.className = body.className&& body.className！=''？ body.className +'has-js'：'has-js'; 
 
 if（！d.getElementById ||！d.createTextNode）return; 
 var ls = gebtn（d，'label'）; 
 for（var i = 0; i  var l = ls [i]; 
 if（l.className.indexOf（'label_'）== -1）continue; 
 var inp = gebtn（l，'input'）[0]; 
 if（l.className =='label_check'）{
 l.className =（safari&& inp.checked == true || inp.checked）？ 'label_check c_on'：'label_check c_off'; 
 l.onclick = check_it; 
}; 
 if（l.className =='label_radio'）{
 l.className =（safari&& inp.checked == true || inp.checked）？ 'label_radio r_on'：'label_radio r_off'; 
 l.onclick = turn_radio; 
}; 
}; 
}; 
 var check_it = function（）{
 var inp = gebtn（this，'input'）[0]; 
 if（this.className =='label_check c_off'||（！safari&& inp.checked））{
 this.className ='label_check c_on'; 
 if（safari）inp.click（）; 
} else {
 this.className ='label_check c_off'; 
 if（safari）inp.click（）; 
}; 
}; 
 var turn_radio = function（）{
 var inp = gebtn（this，'input'）[0]; 
 if（this.className =='label_radio r_off'|| inp.checked）{
 var ls = gebtn（this.parentNode，'label'）; 
 for（var i = 0; i  var l = ls [i]; 
 if（l.className.indexOf（'label_radio'）== -1）continue; 
 l.className ='label_radio r_off'; 
}; 
 this.className ='label_radio r_on'; 
 if（safari）inp.click（）; 
} else {
 this.className ='label_radio r_off'; 
 if（safari）inp.click（）; 
}; 
}; 
< / script> 
  

现在我需要检查复选框被选中或不是..它是在FF工作，但不工作在Chrome和Safari浏览器中。

  if（jQuery（'＃agree_check'）。is（'：checked'））{
 alert（checked）; 
} 
 else 
 {
 alert（Not checked）; 
} 
  

当我选中复选框在FF ..

解决方案

最后，我找到了答案，这只是检查在另一种方式使条件为真，

  if （jQuery（'＃agree_check'）。is（'：checked'）||（jQuery（'div.agree label'）。hasClass（'c_on'）））{
 alert（checked）; 
} 
 else 
 {
 alert（Not checked）; 
} 
  

现在可以在所有浏览器中正常工作。

i used below code for custom checkbox,

HTML

<div class="agree">
                                      <label for="agree_check" class="label_check"><input type="checkbox" class="agree_check" id="agree_check" />Agree</label>
                                  </div>

CSS

.has-js .label_check { padding-left: 34px; }
.has-js .label_check { background: url(../images/box1.png) no-repeat; }
.has-js label.c_on { background: url(../images/box1-with-mark.png) no-repeat; }
.has-js .label_check input { position: absolute; left: -9999px; }

Script

<script type="text/javascript">
var d = document;
var safari = (navigator.userAgent.toLowerCase().indexOf('safari') != -1) ? true : false;
var gebtn = function(parEl,child) { return parEl.getElementsByTagName(child); };
onload = function() {

    var body = gebtn(d,'body')[0];
    body.className = body.className && body.className != '' ? body.className + ' has-js' : 'has-js';

    if (!d.getElementById || !d.createTextNode) return;
    var ls = gebtn(d,'label');
    for (var i = 0; i < ls.length; i++) {
        var l = ls[i];
        if (l.className.indexOf('label_') == -1) continue;
        var inp = gebtn(l,'input')[0];
        if (l.className == 'label_check') {
            l.className = (safari && inp.checked == true || inp.checked) ? 'label_check c_on' : 'label_check c_off';
            l.onclick = check_it;
        };
        if (l.className == 'label_radio') {
            l.className = (safari && inp.checked == true || inp.checked) ? 'label_radio r_on' : 'label_radio r_off';
            l.onclick = turn_radio;
        };
    };
};
var check_it = function() {
    var inp = gebtn(this,'input')[0];
    if (this.className == 'label_check c_off' || (!safari && inp.checked)) {
        this.className = 'label_check c_on';
        if (safari) inp.click();
    } else {
        this.className = 'label_check c_off';
        if (safari) inp.click();
    };
};
var turn_radio = function() {
    var inp = gebtn(this,'input')[0];
    if (this.className == 'label_radio r_off' || inp.checked) {
        var ls = gebtn(this.parentNode,'label');
        for (var i = 0; i < ls.length; i++) {
            var l = ls[i];
            if (l.className.indexOf('label_radio') == -1)  continue;
            l.className = 'label_radio r_off';
        };
        this.className = 'label_radio r_on';
        if (safari) inp.click();
    } else {
        this.className = 'label_radio r_off';
        if (safari) inp.click();
    };
};
       </script>

now i need to check the checkbox is checked or not.. it is works in FF but not works in Chrome and Safari browser.

if (jQuery('#agree_check').is(':checked')) {
alert("checked");
}
else
{
alert("Not checked");
}

when i checked the checkbox it displays "checked" in FF.. but in Chrome and safari it displays "not checked".

what is the issue?

解决方案

Finally i found answer for this, it is just check in another way to make that condition true,

if (jQuery('#agree_check').is(':checked') || (jQuery('div.agree label').hasClass('c_on'))) {
alert("checked");
}
else
{
alert("Not checked");
}

now it's works fine in all browsers.
