For Googler's who may have the same issue: This can happen if you have a non-numeric value in a <code>number</code> type input field. 

For example:

<pre><code>&lt;input type="number" value="&lt;? echo $myNumberValue; ?&gt; "/&gt;
</code></pre>

This will show nothing even though Dev tools says the value is there, since the extra space after <code>?&gt;</code> makes it non-numeric. Simply remove the extra space.

blocks|key|704035|text|您是否混淆了$html->input()的'default‘和'value’参数的用法？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704036|如果您正在使用'default'+=>+$product['Product']['make']，并且存在$this->数据，则不会填充该字段。'+default‘参数的作用是在不存在表单数据($this->+data+)时显示默认值。|offset|length|style|CODE|704037|如果你想强制显示值，你应该改用'+value‘参数。'value'+=>+$product['Product']['make']|704038|entityMap^0|0|7|14|0|Q|12|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@$D|Q|E|R|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|K|$]]

Are you confusing the uses of the 'default' and the 'value' parameters for $html->input()?

If you're are using <code>'default' =&gt; $product['Product']['make']</code> and $this->data is present, the field will not be populated. The purpose of the 'default' parameter is to display a default value when no form data ($this->data) is present.

If you want to force display of a value, you should use the 'value' parameter instead. <code>'value' =&gt; $product['Product']['make']</code>

blocks|key|920522|text|通过ajax检索的输入值也有类似的问题，可以通过浏览器控制台正确设置和验证，但不可见。这个问题是另一个具有相同id的输入域，它并不明显，因为包含了几个JSP文件，其中许多文件都有表单。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|920523|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Had a similar problem with input value retrieved via ajax, correctly set and verifiable via browser console, but not visible. The issue was another input field having the same id, and it was not evident because of several JSP files included, many of them having forms.

blocks|key|704149|text|我甚至将自动完成设置为"off“，但没有任何结果。最后，我把下一个jquery代码片段放在了document.ready活动上。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704150|myForm.find("input").each((i,+el)+=>+{

I even set autocomplete to "off" with no result. I ended up putting the next jquery snippet at the document.ready event.

<pre><code>myForm.find("input").each((i, el) =&gt; {
 $(el).val($(el).attr("value"));
});
</code></pre>

Adittionally, this would be the equivalent in pure es2015:

<pre><code>document.querySelectorAll("myForm input").forEach(el =&gt; {
 el.value = el.getAttribute("value");
});
</code></pre>

If your not using a precompilor like Babel and you need compatibility for old browser's versions, change the "(el) =>" for "function(el)". I tried both codes in my scenario and worked fine.

blocks|key|704173|text|对我来说，这是因为我使用的是<input>标记，而没有将它封装在<form>标记中|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|704174|entityMap^0|E|7|W|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

For me it was because I was using the <code>&lt;input&gt;</code> tag without enclosing it inside a <code>&lt;form&gt;</code> tag

blocks|key|704228|text|对我来说，问题是我有多个具有相同id的输入。我可以看到字段中的值，但通过javascript读取它会得到一个空值，因为它正在读取具有相同id的不同输入-我很惊讶没有javascript错误，只是无法读取我在表单中看到的值。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704229|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For me the problem was that I had multiple inputs with the same id. I could see the value in the field, but reading it via javascript gave an empty value because it was reading a different input with the same id - I was surprised that there was no javascript error, just could not read the values I could see in the form.

For me it was wrong number format: Chrome expected "49.1", but ASP.NET passed "49,1", and it just didn't display!

<pre><code>&lt;input type="number" value="49,1"/&gt; // Should have been 49.1 !!!

blocks|key|920732|text|同样的问题也发生在电子上：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|920733|我使用document.getElementById('_name').value+=+''而不是document.getElementById('_name').setAttribute('value',+"")来清除该字段。|offset|length|style|CODE|920734|所以我猜简单的引号破坏了字段，或者输入有第二个值隐藏属性，因为我可以在字段上重写，而它不会改变检查器上的值|920735|entityMap^0|0|3|17|1D|1M|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]|$D|P|E|Q|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|R|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|K|$]]

Same problem occured on electron:

I was clearing the field with <code>document.getElementById('_name').value = ''</code> instead of <code>document.getElementById('_name').setAttribute('value', "")</code>.

So I guess simple quote broke the field or input has a second value hidden attribute because I could rewrite on the fields and it won't change the value on the inspector

I had the same problem of @Rob Wilkerson, a <code>onchange()</code> was cleaning the value of the input with <code>""</code>, so i changed to <code>1</code>. Such a dumb problem!

<pre><code>HTML
&lt;input class="form-control inputCustomDay" type="text" id="txtNumIntervalo" onkeyup="changeTipoOptions()" value="1" min="1" /&gt;

<pre><code>Jquery

blocks|key|704426|text|我的是和Angular有关的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704427|我最近刚刚遇到了同样的问题，并意识到当您使用NgIf显示模板时，所述模板不会自动使用显示组件中变量的数据。|offset|length|style|CODE|704428|作为一种快速修复方法，我使用ngClass只是为了隐藏和显示它。|704429|entityMap^0|0|M|4|0|E|7|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@$D|Q|E|R|F|G]]|9|@]|A|$]]|$1|J|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|K|$]]

Mine was related to Angular.
I just ran into the same issue recently and realized that when you use <code>NgIf</code> to display a template, the said template does not automatically use display the data from the variables in the component.
As a quick fix I used <code>ngClass</code> just to Hide it and display it.

This must be something utterly stupid that I've done or am doing, but I have an input with a value attribute that simply isn't being displayed:
<pre><code>&lt;div class=&quot;input text required&quot;&gt;
 &lt;label for=&quot;Product0Make&quot;&gt;Make&lt;/label&gt;
 &lt;input name=&quot;data[Product][0][make]&quot; 
 type=&quot;text&quot; 
 maxlength=&quot;255&quot; 
 value=&quot;AC Make&quot; 
 id=&quot;Product0Make&quot;&gt;
&lt;/div&gt;
</code></pre>
Has anyone ever seen this before? Do I have some kind of typo that I'm just blind to? For whatever it may be worth, here's the CakePHP code that's generating this line:
<pre><code>&lt;?php echo $this-&gt;Form-&gt;input( 'Product.' . $index . '.make', array( 'default' =&gt; $product['Product']['make'] ) ) ?&gt;
</code></pre>
I have a small form with a handful of text inputs, 1 textarea and 2 selects. None of the text input values display, but everything else is fine.
Any thoughts would be appreciated. I can't even believe I'm having to ask this question, but that's how crazy it's making me.

Input value doesn't display. How is that possible?

编译器

这一定是我做过或正在做的非常愚蠢的事情，但我有一个带有value属性的输入，它根本没有显示出来：<div class="input text required"> <label for="Product0Make">Make</label> <input name="data[Product][0][make]" type="text" maxlength=
