jquery - 未捕获的类型错误 : Object [object Object] has no method 'live'

Question

收到此错误:

Uncaught TypeError: Object [object Object] has no method 'live'

来自此 JavaScript 和 jQuery 代码:

init: function(options) {
  var form = this;
  if (!form.data('jqv') || form.data('jqv') == null ) {
    options = methods._saveOptions(form, options);
    // bind all formError elements to close on click
    $(".formError").live("click", function() {

      //Getting error here:
      //Uncaught TypeError: Object [object Object] has no method 'live'

    });
  }
  return this;
};

为什么缺少方法live？

Answer 1

.live 在 jquery 1.9 中被删除

请参阅文档:http://api.jquery.com/live/

尝试使用 .on 代替:

$(document).on('click', '.formError', function(){ 
   //your event function
});
