Question

我有这个按钮：

<v-btn @click="handleClick">Save</v-btn>

同一组件用于编辑和创建目的，因此我确实有另一个布尔变量来跟踪组件是否处于编辑/创建模式。现在的问题是，如何更改v-btn的点击处理程序以使其具有不同的处理程序，并且有条件地更改文本？

目前我知道我可以做到：

handleClick() {
    if (editMode) {
        updateData();
    } else {
        createNew();
    }
}
// And this does not solve the problem of having the button's text fixed to "Save"

或者我可以创建两个按钮并有条件地显示它们：

<v-btn v-if="editMode==='true'" @click="updateData">Update</v-btn>
<v-btn v-if="editMode==='false'" @click="createNewData">Save</v-btn>

用单行的v-btn可以做到这一点吗？

Answer 1

添加一个内联处理程序，并根据editMode值有条件地运行该方法，还用于呈现文本：

<v-btn  @click="()=>editMode?updateData():createNewData()">{{editMode?'Update':'Save'}}</v-btn>

Answer 2

您可以存储此按钮的处理程序和相应的标签。

list

names_allowed_to_play = ["MUM","DAD"]

def val_1 (name_1):

    print("Player 1, you have 3 tries to enter the correct name")
    print("")
    a = 0
    
    while a < 3:

        
        name_1 = name_1.upper()

        if name_1 in names_allowed_to_play:
            print(name_1 + ", you are authorised to play, have fun!")
            print("")
            a = a + 4
            names_allowed_to_play.remove(name_1)
            
        elif name_1 not in names_allowed_to_play:
            
            a = a + 1

            if name_1 not in names_allowed_to_play and a ==1:
                print("You have 2 more tries")
                print("")
                print("")
            elif name_1 not in names_allowed_to_play and a ==2:
                print("You have 1 more try")
                print("")
                print("")

    if a == 3:
        print("")
        print("Sorry Player 2, " + name_1 + " ruined it! " + name_1 + ", you are NOT AUTHORISED!")
        sys.exit()
        


#Run definition
name_1 = input("Player 1, please enter your name to play: ")
val_1(name_1)
