Question

我有一个类名，例如“ toxics_decompose（phase）_field1”。

每当我尝试在JQUERY中通过此类名称获取数据时，都会抛出错误

HTML

<textarea rows="4" cols="10" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required ></textarea>
<textarea rows="4" cols="10" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required ></textarea>
<textarea rows="4" cols="10" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required ></textarea>
<textarea rows="4" cols="10" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required ></textarea>
<textarea rows="4" cols="10" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required ></textarea>
OR
<input type="number" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required >
<input type="number" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required >
<input type="number" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required >
<input type="number" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required >
<input type="number" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required >

JQUERY

$(".toxics_decompose(phase)_field1").each(function(i,obj){
    console.log($(this).val());
});

//OR

 [SEC.1] var string=$('input[name^="toxics_decompose(phase)_field1[]"]').serialize();

但是[SEC.1]中没有确定输入类型是文本区域还是数字，因此它如何工作。注意：此处[SEC.1]仅用于参考。

$(".toxics_decompose(phase)_field1").each(function(i, obj) {
  console.log($(this).val());
});

var string = $('input[name^="toxics_decompose(phase)_field1[]"]').serialize();

console.log(string)

<input type="number" class="form-control toxics_decompose(phase)_field1" name="toxics_decompose(phase)_field1[]" placeholder="" required>

在我的方案中，我使用的是数据库获取的名称“ toxics_decompose（phase）_field1”，它会根据更改而有所不同。

JQuery的类选择器包含大括号作为字符串
