如何从javascript中调用jquery中的函数

Question

<script type="text/javascript" src="jscripts/jquery.js"></script>

<script type="text/javascript">
$(document).ready(function(){
alert("funciton");
    $(function(){
        $.fn.gotof(){
            alert("I am calling form jquery");
        }           
    });
});
</script>


<input type="button" onclick="dofunc();">

<script type="text/javascript">
    function dofunc(){
        gotof();
    }
</script>

我如何调用gotof()jquery中存在的内容,以下是在jsfiddle上编写的代码

Answer 1

您的代码中存在一些错误.修正了它应该是这样的:

$.fn.gotof = function() { // has to be defined as a function, does not need to be inside a nested document ready function
    alert("I am calling form jquery");
};

$(document).ready(function() {
    alert("function is ready to use now");
});

function dofunc() {
    $.fn.gotof();  // can call it using $.fn.gotof(), but it should really be called properly via a selector $('div').gotof();
}
