如何为输入文本一起设置值和占位符? [英] How to set a value and placeholder together for input text?
问题描述
我需要为文本框添加提示,我知道可以通过占位符来完成,但是我还需要为同一文本框设置值(初始值应该被隐藏).而不是某些逻辑?
I need to put a hint for a text box.I know it can be done via placeholder , but I also need to set value for the same text box (The initial value should be hidden).Is there any way to that rather than some logic?
这是在我使用html5和jquery-mobile开发移动应用程序时发生的.我正在尝试构建自定义的小时和分钟选择器.插入html的jquery-mobile中是否有任何选项?

推荐答案
通过通过JQM文档标识的标准JQM方法设置占位符值.然后,让JQuery监视用户选择输入字段.然后告诉JQuery在输入字段中添加一个值.
Set the placeholder value via the standard JQM method identified via the JQM docs. Then, have JQuery watch for the user selecting the input field. Then tell JQuery to add a value to the input field.
您可以尝试这样的事情:
You could try something like this:
要使用占位符设置输入字段:
To set an input field with a placeholder:
<input type="text" name="fname" id="input" placeholder="YOUR PLACEHOLDER TEXT">
要添加默认值:
$("#input").focus(function() {
$(this).InnerHTML("ADD DEFAULT VALUE HERE");
});
