问题描述

我知道这里有这篇文章,占位符文本。我已经尝试在我的textarea标记中实现

  textarea ::  -  webkit-input-placeholder {
color: #FFF;
}

textarea:-moz-placeholder {/ * Firefox 18- * /
color:#fff;
}

textarea :: - moz-placeholder {/ * Firefox 19+ * /
color:#fff;
}

textarea:-ms-input-placeholder {
color:#fff;
}

但它没有做任何事情。我缺少什么?



这就是我的 textarea 中的一个看起来像

 < textarea 
onChange = {(e)=> this.props.handleUpdateQuestion(e,firstQuestion.Id)}
placeholder =整体满意度问题
name =SEO__Question__c
type =text
className =slds -input
value = {firstQuestion.SEO__Question__c? firstQuestion.SEO__Question__c:''}
style = {inputStyle}
autoFocus
/>


解决方案

...也许尝试设置一些引号?

  onchange ={(e)=> this.props.handleUpdateQuestion(e,firstQuestion.Id)}

否则应该正常工作:

  textarea ::  -  webkit-input-placeholder {color:#0bf;} textarea:-moz-placeholder {/ * Firefox 18- * / color:# 0bf; } textarea ::  -  moz-placeholder {/ * Firefox 19+ * / color:#0bf; } textarea:-ms-input-placeholder {color:#0bf; }  

< textarea placeholder =test>< ; / textarea>


I know there is this post on changing the placeholder text. I've tried implementing in on my textarea tags

textarea::-webkit-input-placeholder {
color: #fff;
}

textarea:-moz-placeholder { /* Firefox 18- */
color: #fff;  
}

textarea::-moz-placeholder {  /* Firefox 19+ */
color: #fff;  
}

textarea:-ms-input-placeholder {
color: #fff;  
}

but it's not doing anything. What am I missing?

This is what one of my textarea's looks like

<textarea
  onChange={(e) => this.props.handleUpdateQuestion(e, firstQuestion.Id)}
  placeholder="Overall Satisfaction Question"
  name="SEO__Question__c"
  type="text"
  className="slds-input"
  value={firstQuestion.SEO__Question__c ? firstQuestion.SEO__Question__c : ''}
  style={inputStyle}
  autoFocus
/>

解决方案

...perhaps try to set some quotes?

onchange="{(e) => this.props.handleUpdateQuestion(e, firstQuestion.Id)}"

otherwise should work just fine:

textarea::-webkit-input-placeholder {
color: #0bf;
}

textarea:-moz-placeholder { /* Firefox 18- */
color: #0bf;  
}

textarea::-moz-placeholder {  /* Firefox 19+ */
color: #0bf;  
}

textarea:-ms-input-placeholder {
color: #0bf;  
}

<textarea placeholder="test"></textarea>
