我需要一个帮助.我需要通过获取id来检查单选按钮,并使用
Javascript / Jquery进行验证.我在下面解释我的代码
<div>
<input type="radio" name="rd0" value="57db18">Raj
<input type="radio" name="rd0" value="57da17">Rahul
<input type="radio" name="rd0" value="57db19">Mona
</div>
<br>
<br>
<div>
<input type="radio" name="rd1" value="57db18">A
<input type="radio" name="rd1" value="57da17">B
<input type="radio" name="rd1" value="57db19">C
</div>
<br>
<br>
<div >
<input type="radio" name="rd2" value="57db18">Apple
<input type="radio" name="rd2" value="57da17">Orange
<input type="radio" name="rd2" value="57db19">Mango
</div>
<span>
<button type="button" id="btn" name="btn" onclick="setValue()">Set</button>
</span>
<span>
<button type="button" id="vbtn" name="vbtn" onclick="validateradioButtonValue()">Validate</button>
</span>
在这里我有3套单选按钮,当用户点击设置按钮时,单选按钮应该按循环中的给定值进行检查.脚本部分如下.
var valu = ['57da17','57db18','57db19'];
function setValue(){
for(var i=0;i<valu.length;i++){
$('#rd'+i+'[value="' + valu[i]+ '"]').prop('checked',true);
console.log('checked btn',$('#rd'+i).is(':checked') );
}
}
但是在目前的情况下,它没有发生.当用户也将点击验证按钮时,应该检查所有单选按钮是否被检查.请帮助我.
解决方法
尝试这个 ：
$(‘input [name = rd’i’] [value =“’valu [i]’”]’).prop(‘checked’,true)
var valu = ['57da17','57db19'];
function setValue(){
for(var i=0;i<valu.length;i++){
$('input[name=rd'+i+'][value="' + valu[i]+ '"]').prop('checked',$('input[name=rd' + i + ']').is(':checked') );
}
}
