PHP页面输出时js设置input框的选中值

/* 设置表单的值 */
function setValue(name, value) {
var first = name.substr(0, 1),
input, i = 0,
val;
if (value === "") return;
if ("#" === first || "." === first) {
input = $(name);
} else {
input = $("[name='" + name + "']");
}

if (input.eq(0).is(":radio")) { //单选按钮
input.filter("[value='" + value + "']").each(function() {
this.checked = true
});
} else if (input.eq(0).is(":checkbox")) { //复选框
if (!$.isArray(value)) {
val = new Array();
val[0] = value;
} else {
val = value;
}
for (i = 0, len = val.length; i < len; i++) {
input.filter("[value='" + val[i] + "']").each(function() {
this.checked = true
});
}
} else { //其他表单选项直接设置值
input.val(value);
}
}
