Question

我有一个页面，其中包含如下事件：

$(document).on("click","#div",function(e){

//do the operation

});

此事件在页面加载和div单击时执行。我需要区分事件中的这两个调用，因为我必须在div点击而不是加载时写一个额外的条件。

如何知道页面加载或div点击？

修改

载入时：

$（默认）.find（＆＃39; a＆＃39;。）触发器（＆＃34;点击＆＃34;）;使其在加载时触发

Answer 1

＆＃13;

$(document).on("click", "#div", function(e) {

  if (e.originalEvent !== undefined) {//use the originalEvent
    alert('human');
  } else {
    alert('load click')
  }

});


$('#div').click();

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='div'>click</div>

#include <boost/graph/adjacency_list.hpp>
#include <boost/graph/graphviz.hpp>
using std::map;

template <typename Map>
struct my_node_writer {
    // my_node_writer() {}
    my_node_writer(Map& g_) : g (g_) {};
    template <class Vertex>
    void operator()(std::ostream& out, Vertex v) {
        out << " [label=\"" << v << "\"]" << std::endl;
    };
    Map g;
};

template <typename Map>
my_node_writer<Map> node_writer(Map& map) { return my_node_writer<Map>(map); }

template <typename Map>
struct my_edge_writer {
    my_edge_writer(Map& g_) : g (g_) {};
    template <class Edge>
    void operator()(std::ostream& out, Edge e) {

        out << " [color=purple]" << std::endl;
        out << " [label=\"" << e  <<":" << g[e].miles << "\"]" << std::endl;
    };
    Map g;
};

template <typename Map>
my_edge_writer<Map> edge_writer(Map& map) { return my_edge_writer<Map>(map); }

struct my_graph_writer {
    void operator()(std::ostream& out) const {
        out << "graph [bgcolor=lightgrey]" << std::endl;
        out << "node [shape=circle color=blue]" << std::endl;

        out << "edge [color=red]" << std::endl;
    }
} myGraphWrite;

struct edge_prop
{
    int miles;
};

int main()
{
    using namespace boost;
    typedef adjacency_list<vecS, vecS, directedS, no_property, edge_prop> Graph;
    Graph g;
    add_edge(0, 1, edge_prop{123}, g);

    write_graphviz(std::cout,g,node_writer(g),edge_writer(g),myGraphWrite);

}

＆＃13;

//You can check for originalEvent element present in event object.
$(document).ready(function() {

  $(document).on("click","#div",function(e){

    if(e.originalEvent) {
      alert('clicked manually');
    } else {
      alert('page load');
    }

  });

  $('#div').click();

});

你可以在每个中设置一个布尔变量，如：

<OperationTypes xmlns="http://www.example.com/aaa/2011" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 <OperationType Uri="http://localhost:8012/Enterprise/OperationTypes/a1d02dac-c454-497b-808d-a619009c7c7e" Name="test" Number="19" Active="true" Description="" SetupCalculation="PerWorkOrder" Side="" />
<OperationType Uri="http://localhost:8012/Enterprise/OperationTypes/07102c89-93e1-499b-980e-a61900cf2217" Name="OT_Prakash" Number="20" Active="false" Description="" SetupCalculation="PerWorkOrder" Side="" />
</OperationTypes>

然后使用if或switch语句检查哪个条件为真。

如果您需要对页面加载执行任何操作，则必须指定如下

$(document).load(function(){
  alert("event on page load");
});

如果div点击事件，则如下

$(#div).onclick(function(){ alert ("on div click"); })
