Baidu Search
Var v = new Vue ({
El: "# div1", / / valid range of vue. You cannot use body directly.
Data: {/ / vue data required by the page
Href: "https://www.baidu.com"
}
});
Well, it's simple, so what if you need to display text with variables?
View
Var v = new Vue ({
El: "# div1", / / valid range of vue. You cannot use body directly.
Data: {/ / vue data required by the page
Id: 3
}
});
I see, you need to concatenate strings, like v-bind: can be abbreviated to: I'll try it in the next example.
Next I'll try the style binding.
Var v = new Vue ({
El: "# div1", / / valid range of vue. You cannot use body directly.
Data: {/ / vue data required by the page
ShowStyle: false
}
});
Yes, it can really be abbreviated, and the style binding seems to be a little different from other ones.
What about the binding of events?
It turns out that v-on is used to bind event operations, and you can also use @ instead of v-on.
Var v = new Vue ({
El: "# div1", / / valid range of vue. You cannot use body directly.
Data: {/ / vue data required by the page
BtnValue: "Click"
}
Methods: {/ / functions of vue available to the page
Fn1: function () {
Alert (this.msg)
}
Fn2: function () {
This.btnValue = "Click"
}
}
});
