jQuery中用.each遍历输入框举例

<div class="comment">a</div><div class="setconf"><input id="8b5b65773d4d741895b957355855fb53" class="ip" value="2" maxlength="15" size="15" type="text"></div><p></p><p></p><div class="comment">bbb</div><div class="setconf"><input id="c42d4f7a2f7e83f6f529ef64aaebd58f" class="ip" value="1" maxlength="15" size="15" type="text"></div><p></p><p></p><div class="comment">ccc</div><div class="setconf"><input id="f37620d47962c958cfe4052cf0acf0bd" class="ip" value="1048576" maxlength="15" size="15" type="text"></div><p></p><p></p><div class="comment">ddd</div><div class="setconf"><input id="e31b9704455e99dd83520f1ab6301b9f" class="ip" value="1048576" maxlength="15" size="15" type="text"></div><p></p><p></p><div class="comment">eee</div><div class="setconf"><input id="ab6b298e6e7d1b53fdca88ec03932256" class="ip" value="1048576" maxlength="15" size="15" type="text"></div><p></p><p></p><div class="comment">ffff</div><div class="setconf"><input id="9f34447b175145b4cdce9cb4db8af792" class="ip" value="1048576" maxlength="15" size="15" type="text"></div><p></p><p><span aria-disabled="false" role="button" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" id="submit"><span class="ui-button-text">提交</span></span><span aria-disabled="false" role="button" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" id="reset"><span class="ui-button-text">取消</span>

$.each($("#content :input"),function(k ,v){
    alert("key:"+k+"____value:" + v.value + "___ID: " + v.id);
    }
);
