JavaScript:为什么代码不能用于点击功能

标签: javascript jquery html forms

我想使用click()函数在HTML中返回表单的属性和值,然后将它们添加到字符串中。 这是我的代码。对于“表单”,我只想获得这些值一次,而“输入”标签可以被多次检索:

var target="http://www.aaa.com/";
var clicktime=0;

$(document).ready(function(){
    $("form").click(function(){
    var c=this.method;
    var d=this.action;
    var e=d.substr(17)
    $("#test2").text("the method is:   " +c+"   "+"The action part is:"+ "    "+e);
    if (clicktime=0){
    target=target+e+"?";
    }
    clicktime=1;
    $("#test1").text("you choose the following links:"+ "    "+target);
    });
});

$(document).ready(function(){

    $("input").click(function(){
    var a=this.name;
    var b=this.value;
    target=target+a+"="+b+"&";
    $("#test1").text("you choose the following links:"+ "    "+target);
    });
});

点击浏览器中的表单部分后,结果应如下所示:

the method is get The action part is /dec/DEC

you choose the following links: http://www.aaa.com/

虽然我在浏览器中单击表单部分的结果是:

the method is get The action part is /dec/DEC

you choose the following links: http://www.aaa.com/dec/DEC

“target = target + e +”?“;没有用!为什么?类似的功能在”输入“功能上运行良好!

if (clicktime=0)

应该是

if (clicktime==0)

=是一个赋值运算符。 ==是比较运算符。
