代码如下:
function doGender(gender) {
if (gender == "男") {
gel("radionan").checked = true
} else {
gel("radionv").checked = true
}
}
扩展资料
JS基础代码:
//定义数组
var pageIds = new Array()
pageIds.push('A')
数组长度
pageIds.length
//shift:删除原数组第一项,并返回删除元素的值;如果数组为空则返回undefined
var a = [1,2,3,4,5]
var b = a.shift()//a:[2,3,4,5] b:1
//unshift:将参数添加到原数组开头,并返回数组的长度
var a = [1,2,3,4,5]
var b = a.unshift(-2,-1)//a:[-2,-1,1,2,3,4,5] b:7
//注:在IE6.0下测试返回值总为undefined,FF2.0下测试返回值为7,所以这个方法的返回值不可靠,需要用返回值时可用splice代替本方法来使用。
设置radio的checked属性为ture即为选中。<input type="radio" id="radioId" value="1" >
选中单选框JS代码:
var target = document.getElementById("radioId")
target.checked = true
