复选框检查事件监听器 [英] Checkbox Check Event Listener
问题描述
最近我一直在使用Chrome插件API,我正在开发一个插件,这将使我更容易管理一个网站。
我希望做的是在某个复选框被选中时触发一个事件。
由于本网站不属于我,我无法更改代码,因此我使用的是Chrome API。其中一个主要问题是,不是存在ID,而是存在名称。
谢谢
< input type =h2_lin>解决方案
复选框name =复选框>
没有jQuery
使用jQuery-如 querySelector 。
var checkbox = document.querySelector(input [name = checkbox]);
checkbox.addEventListener('change',function(){
if(this.checked){
// Checkbox is checked ..
} else {
//复选框未被选中。
}
});
使用jQuery
< ($(this).is(':checked')){
// Checkbox($)$('input [name = checkbox]')。被检查。
} else {
//复选框未被选中。
}
});
Recently I have been working with the Chrome Plugin API and I am looking to develop a plugin which will make life easier for me for managing a website.
Now what I wish to do is to fire an event when a certain checkbox is checked. As this website does not belong to me I cannot change the code therefore I am using the Chrome API. One of the main problems is that rather than there being an ID, there is a Name. I was wondering if I could fire the function once the certain checkbox with the 'name' is checked.
Thanks
Assuming you're using this markup:
<input type="checkbox" name="checkbox">
Without jQuery
Using the jQuery-like querySelector.
var checkbox = document.querySelector("input[name=checkbox]");
checkbox.addEventListener( 'change', function() {
if(this.checked) {
// Checkbox is checked..
} else {
// Checkbox is not checked..
}
});
With jQuery
$('input[name=checkbox]').change(function(){
if($(this).is(':checked')) {
// Checkbox is checked..
} else {
// Checkbox is not checked..
}
});
