What it is the jQuery equivalent function of Javascript DafaultValue()

Question

I want to get the default value of an input textbox when the page was loaded. As I searched around I saw that the DefaultValue() is a method to get a value from a textbox when is loaded . But what is the jQuery one?

<input id=text > </input>

<script>
$(#text).DefaultValue(); // This is wrong I need the Jquery function of this
</script>

Any Idea?

您可以defaultValue像这样读取DOM属性:

$('#text').prop('defaultValue')

这是一个有效的例子

$('#value').click(function(){
    alert($('#text').val())  
});

$('#def').click(function(){
    alert($('#text').prop("defaultValue"))  
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="text" value="This is the default value">
<button id="value">Click to see the current value</button>
<button id="def">Click to see the default value</button>
