jquery 解析 json数据

<script type="text/javascript">
$(document).ready(function(){
$("#button").click(function(){
alert ("good");

$.getJSON("http://localhost/index.php/users", function(json){
         
$.each(json, function(idx, obj) {
             
                 
                    alert(obj.name);
           
             });


       });
});
});
</script>
json格式:
[{"user_id":"2","username":"guest2","name":"John","profile_pic":""},{"user_id":"1","username":"guest","name":"tom","profile_pic":""}]
json的格式对于解析非常重要,一定要规范化

javascipt 模拟测试


 

  
 
 
12*12=?


122 124 134 144
11*11=?
122 131 121 111
这个结果和实际不相符的原因是blgspot可能对html进行了加工,在正常的网页中正常显示
document.forms[0];是指获取第一个form
另外,这种单选框的name必须一直才能保证单选

显示效果:



12*12=?

122
124
134
144

11*11=?
122
131
121
111

一个简单 javascript计算器的实现

<input id="kkk" />

<br />
<button id="1" onclick="reply_click(this.value)" value="1">1</button>
<button id="2" onclick="reply_click(this.id)">2</button>
<button id="3" onclick="reply_click(this.id)">3</button>
<button id="4" onclick="reply_click(this.id)">4</button>
<button id="5" onclick="reply_click(this.id)">5</button>
<button id="6" onclick="reply_click(this.id)">6</button>
<button id="7" onclick="reply_click(this.id)">7</button>
<button id="8" onclick="reply_click(this.id)">8</button>
<button id="9" onclick="reply_click(this.id)">9</button>
<button id="0" onclick="reply_click(this.id)">0</button>
<br />
<button id="equal" onclick="compute()">=</button>
<button onclick="reply_click(this.value)" value="+">+</button>
<button onclick="reply_click(this.value)" value="-">-</button>
<button onclick="reply_click(this.value)" value="*">*</button>
<button onclick="reply_click(this.value)" value="/">/</button>
<button onclick="reset()">C</button>


<script type="text/javascript">
function reply_click(clicked_id)
{
    document.getElementById("kkk").value+=clicked_id;
}
function compute()
{
document.getElementById("kkk").value = eval(document.getElementById("kkk").value);
}
function reset()
{
document.getElementById("kkk").value="";
}

</script>

效果见
