trying to get these fields like:
试图获得这些字段，如：
$('input[name="pages_title[]"]')
but have empty results :(
但结果为空:(
how to get all fields?
I can only get it like $('input[name="pages_title[1]"]')
如何获取所有字段？我只能得到它$('input[name="pages_title[1]"]')

Use the starts with selector
使用以选择器开头
$('input[name^="pages_title"]').each(function() {
alert($(this).val());
});
Note:In agreement with @epascarello that the better solution is to add a class to the elements and reference that class.
注意：与@epascarello 一致认为更好的解决方案是向元素添加一个类并引用该类。

this usualy works on Checkboxes and Radio buttons... but, each name should be the same.
这通常适用于复选框和单选按钮......但是，每个名称都应该相同。
<input type="text" value="2" name="pages_title[]">
<input type="text" value="1" name="pages_title[]">
var x = $('input[name="pages_title[]"]').val();
that is "supposed" to get you all the fields in comma separated values. never tried it with text boxes, so cant guarantee it.
那是“应该”让您以逗号分隔值获取所有字段。从来没有用文本框试过，所以不能保证。
as @John commented:
to iterate over them.
$('input[name="pages_title[]"]').each(function() { var aValue = $(this).val(); });
正如@John 评论的那样：迭代它们。
$('input[name="pages_title[]"]').each(function() { var aValue = $(this).val(); });
EDIT: Not allways you need just to answer the OP questions, sometimes you need to teach them better methods. (sorry if that sounds Arrogant)
编辑：并非总是你只需要回答 OP 问题，有时你需要教他们更好的方法。（对不起，如果这听起来很傲慢）
COMMENT: defining inputs as
评论：将输入定义为
<input type="text" value="1" name="pages_title[1]">
<input type="text" value="2" name="pages_title[2]">
is breaking the array, each input has a unique name, therefor, it is not an array anymore.
正在破坏数组，每个输入都有一个唯一的名称，因此，它不再是数组。

use map method we can get input values that stored in array.
使用 map 方法我们可以获得存储在数组中的输入值。
var values = $("input[name='pages_title[]']").map(function(){return $(this).val();}).get();
回答by epascarello
You need to use the starts with selector
var elems = $( "[name^='pages_title']" );
But a better solution is to add a class to the elements and reference the class. The reason it is a faster look up.
但是更好的解决方案是向元素添加一个类并引用该类。原因是查找速度更快。

Put the input name between single quotesso that the brackets []are treated as a string
将输入名称放在单引号之间，以便将括号[]视为字符串
var multi_members="";
$("input[name='bayi[]']:checked:enabled").each(function() {
multi_members=$(this).val()+","+multi_members;
});

You can give your input textboxes class names, like so:
您可以为输入文本框提供类名称，如下所示：
<input type="text" value="2" name="pages_title[1]" class="pages_title">
<input type="text" value="1" name="pages_title[2]" class="pages_title">
and iterate like so:
并像这样迭代：
$('input.pages_title').each(function() {
alert($(this).val());
});

I think the best way, is to use a Propper Form and to use jQuery.serializeArray.
我认为最好的方法是使用 Propper Form 并使用jQuery.serializeArray。
<!-- a form with any type of input -->
<form class="a-form">
<select name="field[something]">...</select>
<input type="checkbox" name="field[somethingelse]" ... />
<input type="radio" name="field[somethingelse2]" ... />
<input type="text" name="field[somethingelse3]" ... />
</form>
<!-- sample ajax call -->
<script>
$(document).ready(function(){
$.ajax({
url: 'submit.php',
type: 'post',
data: $('form[name="a-form"]).serializeArray(),
success: function(response){
...
}
});
});
</script>
The Values will be available in PHP as $_POST['field'][INDEX].
这些值将在 PHP 中以$_POST['field'][INDEX].
回答by Henry
You can escape the square brackets with double backslashes like this:
您可以像这样使用双反斜杠转义方括号：
$('input[name="pages_title\\[\\]"]')
$('input[name="pages_title\\[\\]"]')

You may use the contain selector:
您可以使用包含选择器：
[name*=”value”]: selects elements that have the specified attribute with a value containing a given substring.
[name*=”value”]：选择具有包含给定子字符串的值的指定属性的元素。
$( document ).on( "keyup", "input[name*='pages_title']", function() {
alert($(this).val());
});

In order to select an element by attribute having a specific characteristic you may create a new selector like in the following snippet using a regex pattern. The usage of regex is intended to make flexible the new selector as much as possible:
为了通过具有特定特征的属性选择元素，您可以使用正则表达式模式创建一个新的选择器，如下面的代码片段所示。regex 的使用旨在使新选择器尽可能灵活：
jQuery.extend(jQuery.expr[':'], {
nameMatch: function (ele, idx, selector) {
var rpStr = (selector[3] || '').replace(/^\/(.*)\/$/, '');
return (new RegExp(rpStr)).test(ele.name);
}
});
//
// use of selector
//
$('input:nameMatch(/^pages_title\[\d\]$/)').each(function(idx, ele) {
console.log(ele.outerHTML);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" value="2" name="pages_title[1]">
<input type="text" value="1" name="pages_title[2]">
<input type="text" value="1" name="pages_title[]">Another solution can be based on:
另一种解决方案可以基于：
[name^=”value”]: selects elements that have the specified attribute with a value beginning exactly with a given string.
.filter(): reduce the set of matched elements to those that match the selector or pass the function's test.
[name^=”value”]：选择具有指定属性的元素，该属性的值恰好以给定的字符串开头。
.filter()：将匹配元素集减少到与选择器匹配或通过函数测试的元素集。
- a regex pattern
- 正则表达式模式
var selectedEle = $(':input[name^="pages_title"]').filter(function(idx, ele) {
//
// test if the name attribute matches the pattern.....
//
return /^pages_title\[\d\]$/.test(ele.name);
});
selectedEle.each(function(idx, ele) {
console.log(ele.outerHTML);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" value="2" name="pages_title[1]">
<input type="text" value="1" name="pages_title[2]">
<input type="text" value="1" name="pages_title[]">
