对于模糊的标题,我们深表歉意。我有一个我正在为我经常访问的网站工作的用户脚本。我正在编辑一个被遗弃的页面,使其再次成为客户端的半工作。我无法向您展示页面,但我可以向您展示您应该需要的一切。
编辑:我正在尝试更新一个不起作用的表单,我不确定还能说些什么。我的剧本:
var form = document.getElementByTagName("FORM")[0];
var form_new = document.createElement("FORM");
var form_table = document.createElement("TABLE");
var form_submit = document.createElement("INPUT");
var form_input = [{
"type" : "hidden",
"name" : "securitytoken",
"value" : "1384271912-8dbdaf1d1f16d4d6e0a33bf3a1b184c6add5b295"
},{
"type" : "hidden",
"name" : "do",
"value" : "archive"
},{
"type" : "hidden",
"name" : "search",
"value" : "1"
},{
"type" : "text",
"name" : "search[phrase]",
"value" : "",
"label" : "Shout Contains"
},{
"type" : "text",
"name" : "search[username]",
"value" : "",
"label" : "Username Contains"
},{
"type" : "text",
"name" : "search[time]",
"value" : "999999999999",
"label" : "Time"
},{
"type" : "text",
"name" : "perpage",
"value" : "50",
"label" : "Per Page"
},{
"type" : "select",
"name" : "search[sort]",
"option" : [{
"value" : "new",
"text" : "Newest first"
},{
"value" : "old",
"text" : "Oldest first"
}],
"label" : "Sort by"
}];
for(var a = 0; a < form_input; a++){
var tr = document.createElement("TR");
var td1 = document.createElement("TD");
var td2 = document.createElement("TD");
var input = document.createElement("INPUT");
var select = document.createElement("SELECT");
var el = form_input[a];
if(el.type !== "hidden"){
var td1_text = document.createTextNode(el.label);
td1.appendChild(td1_text);
if(el.type == "select"){
var select_options = el.option;
for(var b = 0; b < select_options.length; b++){
var select_option = document.createElement("OPTION");
select_option.setAttribute("value",select_options[b].value);
var select_option_text = document.createTextNode(select_options[b].text);
select_option.appendChild(select_option_text);
select.appendChild(select_option);
}
td2.appendChild(select);
}else{
input.setAttribute("type",el.type);
input.setAttribute("name",el.name);
input.setAttribute("value",el.value);
td2.appendChild(input);
}
tr.appendChild(td1);
tr.appendChild(td2);
form_table.appendChild(tr);
}else{
input.setAttribute("type",el.type);
input.setAttribute("name",el.name);
input.setAttribute("value",el.value);
form_new.appendChild(input);
}
}
form_new.appendChild(form_table);
form.innerHTML = '';
form.setAttribute("style","position:fixed;\
bottom:4px;\
right:4px;\
padding:4px;\
background:#ddd;\
border-radius:10px;\
border:solid 1px black;");
form.setAttribute("method","POST");
form.setAttribute("action","boxoshouts.php?do=archive");
form_submit.setAttribute("type","submit");
form_submit.setAttribute("class","button");
form_submit.setAttribute("value","Submit");
form_new.appendChild(form_submit);
form.appendChild(form_new);
表格我正在更新:
<form method="post" action="iarchive.php">
<input type="hidden" name="do" value="archive">
<input type="hidden" name="search" value="1">
</form>
你觉得这有什么问题吗?因为我已经多次重复它并没有发现任何错误。它在控制台中也没有错误,并且FORM确实存在,并且是页面上的第一个也是唯一一个。
答案 0 :(得分:0)
首先:
for(var a = 0; a < form_input; a++){
应该是
for (var a = 0; a < form_input.length; a++) {
此外,您不必使用.setAttribute()
来设置DOM元素属性:
input.type = el.type;
input.name = el.name;
input.value = el.value;
