我创建了jquery插件,看起来像这样:
(function ( $ ) {
// -- This is Person Object used for plugin
var PersonObject = function(elem, options)
{
this.elem = elem;
this.options = options;
this.run();
};
PersonObject.prototype = {
run: function()
{
// console.log(this.options.person_name);
self = this;
tpl = '<a class="btn btn-link btncok">one</a>';
self.elem.after(tpl);
$('.content').on('click', '.btncok', function(e) {
e.stopImmediatePropagation();
self.show();
});
return self.options.person_name;
},
show: function()
{
console.log(this.options.person_name);
}
};
// -- end Person Object
// -- This is my jquery fn function
$.fn.myPlugin = function(options) {
// here is default options
var default_options = {person_name: 'father'};
options = $.extend({}, default_options, options);
return this.each(function() {
new PersonObject($(this), options);
});
};
// -- end jquery plugin
}( jQuery ));
。
那么,当上述插件被许多具有不同情况的元素使用时:
<div class="jumbotron content">
<p class="something-one">one</p>
<p class="something-two">two</p>
</div>
<script>
// call the plugin WITH parameters
$('.something-one').myPlugin({person_name: 'mother'});
// result wrong : father (should be mother)
// call the plugin WITHOUT parameters
$('.something-two').myPlugin();
// result correct : father
</script>
参数不能正常工作。
使用插件的所有元素将通过最后一个元素调用接收相同的参数

由于以下点击处理程序
,您看到相同的值$('.content').on('click', '.btncok', function(e) {
e.stopImmediatePropagation();
self.show();
});
$('.content').on('click', '.btncok', ....
不会按预期委托事件。而是直接将事件附加到tpl
。像这样的东西
this.appendedEl = $('<a class="btn btn-link btncok">'+this.options.person_name+'</a>');
this.elem.after(this.appendedEl);
this.appendedEl.on('click', function(e) { // <--- this way the event is attached to the right element
e.stopImmediatePropagation();
this.show();
}.bind(this)); // <--- I used bind instead of self
