如果单击新的Entry按钮，则会出现该新添加对象的布局问题。

If the new Entry Button is clicked, there is an layout issue for that new added object.

文本框样式为：

file.setAttribute("style", "margin-top: 60px;");

但我想让文本框在中间而不是在底部。我试过自己，但它不适用于我。任何人都可以帮助我解决这个问题？

But I want the text box to be in the middle and not at the bottom. I tried myself but it doesn't works for me. Anybody could help me to solve this problem?

推荐答案

您的代码是非常复杂的，所以这可能有帮助：

Your code is extremely complicated to read, so this may help:

HTML：

<form name="addpoll">

<div id="choices">


</div>
<input id="addchoice" type="button" value="Add New Entry">

</form>

JS：

function addnewDiv(counterAppended) {
    counterAppended = parseInt(counterAppended) + 1;
    var text = document.createElement("div");
    text.innerHTML = '<input type="hidden" class="choicecount" name="choicecount" id="choicecount" value="' + counterAppended + '">\
<input type="file" name="choiceimg' + counterAppended + '" value ="Select"  onchange="readURL(this)" style="display:none;">\
<div>\
<div style="width:400px;height:85px;">\
<div id="imgbg" style="float:left;width: 110px;height: 80px;text-align: center;border: 1px solid #CCC;">\
<input type="button" onclick="HandFileButtonClick();"  value="Browse" id="firstremove" style="margin-top: 30px;" class="addmultiple">\
</div>\
<div style="float:right;margin-top: 30px;">\
<input type=text name="choicename' + counterAppended + '" id="firstremove2">\
<input type="button" value="Remove" class="remove" id="firstremove3" style="color: red; font-size: 12px; border: 0px; background: none; text-decoration: underline;">\
</div>\
</div>\
<img src="#" name="viewimg' + counterAppended + '" class="addmultiple" id="viewimg' + counterAppended + '" height="70px" width="85px" style="display:none"/>\
<br>\
</div>\
<span id="file"></span>';
    text.id = 'choice' + counterAppended;
    document.getElementById("choices").appendChild(text);
    document.getElementsByClassName("remove")[document.getElementsByClassName("remove").length - 1].addEventListener("click", function() {
        this.parentNode.parentNode.parentNode.parentNode.removeChild(this.parentNode.parentNode.parentNode);
    });
}

function HandFileButtonClick() {
    document.addpoll.choiceimg1.click();
}

function HandleFileButtonClick(val) {
    var ss = val.name;
    document.forms["addpoll"]
    var n = ss.split("choiceimgs");
    document.forms["addpoll"]["choiceimg" + n[1]].click();
}
document.getElementById("addchoice").addEventListener("click", function() {
    var choicecounts = document.getElementsByClassName('choicecount');
    addnewDiv(choicecounts[choicecounts.length - 1].value);
});

addnewDiv(0);
