你應(yīng)該是想全局替換某一個(gè)關(guān)鍵字。
阿里地區(qū)網(wǎng)站制作公司哪家好，找創(chuàng)新互聯(lián)公司！從網(wǎng)頁(yè)設(shè)計(jì)、網(wǎng)站建設(shè)、微信開(kāi)發(fā)、APP開(kāi)發(fā)、成都響應(yīng)式網(wǎng)站建設(shè)等網(wǎng)站項(xiàng)目制作，到程序開(kāi)發(fā)，運(yùn)營(yíng)維護(hù)。創(chuàng)新互聯(lián)公司2013年至今到現(xiàn)在10年的時(shí)間，我們擁有了豐富的建站經(jīng)驗(yàn)和運(yùn)維經(jīng)驗(yàn)，來(lái)保證我們的工作的順利進(jìn)行。專注于網(wǎng)站建設(shè)就選創(chuàng)新互聯(lián)公司。
選定文本域之后，按下Ctrl + F，選擇里面的相關(guān)選項(xiàng)即可，我認(rèn)為你可以看懂。
//多選框
table?id='tab'?width="300"
tr
tdlabelinput?name="mk"?type="checkbox"?value="1"?/XX/label/td
tdlabelinput?name="mk"?type="checkbox"?value="1"?/XX/label/td
/tr
/table
//全選全部選按鈕
input?type="button"?value="全選"??style="width:50px"??id="selectAll"
input?type="button"?value="全不選"?style="width:50px"?id="unSelect"
//事件
$("#selectAll").click(function?()?{
$("#tab?:checkbox,#all").prop("checked",?true);??
});
$("#unSelect").click(function?()?{??
$("#tab?:checkbox,#all").prop("checked",?false);??
});
這是我之前寫(xiě)的? 你照著改改吧
function selall(obj){
for (var i=0;iobj.elements.length;i++){
var e = obj.elements[i];
if (e.name == 'idd'){
var v=e.checked;
break;
}
}
for (var i=0;iobj.elements.length;i++){
var e = obj.elements[i];
if (e.name == 'id')
e.checked = v;
}
}
全選/反選td style="width:50px;" class="edit"input type="checkBox" name="idd" value="1" onClick="selall(f1)"/td
刪除 td style="width:50px;" class="edit"input type="checkBox" name="id" value="${aa.NId}"/td
用jquery 腳本實(shí)現(xiàn)吧兄弟
為選擇按鈕注冊(cè)點(diǎn)擊事件{
$(".每一個(gè)車位div").attr( 屬性名: 屬性值);
}
讓每一個(gè)車位都有相同的class
attr 后面就為他設(shè)置style就好了
