Question

当用户单击按钮时，我必须显示数据库中的联系人编号。但是当我在javaScript中使用php时，它对我不起作用... 这是HTML

class BurgerForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(BurgerForm, self).__init__(*args, **kwargs)
        self.fields['toppings'].widget = forms.CheckboxSelectMultiple()
        for field_name in self.fields:
            field = self.fields.get(field_name)
            if field and isinstance(field , forms.TypedChoiceField):
                field.choices = field.choices[1:]
        self.fields['extras'].widget = forms.CheckboxSelectMultiple()

    class Meta:
        model = Burger
        fields = ['burger', 'bun', 'toppings', 'sauces', 'extras']

<button name="showNo" id="phone1" onclick="myFunction()"><span>Show Phone No</span></button>

此处是JavaScript

<p id="show">******</p>

还有其他方法可以做到吗？

Answer 1

尝试一下，p标签没有值，因此您需要使用innerHTML从中获取数据并进行设置

var hsh = document.getElementById("show").innerHTML;
if(hsh === "******"){
    document.getElementById('show').innerHTML = "<?php echo $contact; ?>";
}else{
    document.getElementById('show').innerHTML = "<?php echo 'Open Curtain'; ?>";
}

如何在JavaScript中使用PHP？
