getTemp是JQL语法，云函数只有启用了JQL扩展才支持

启用了也报错，写在云对象里

回复 西西11: jql不只是启用了就行，你还需要调用uniCloud.databaseForJQL()方法

回复 DCloud_uniCloud_WYQ: 这有用，关键词databaseForJQL

The error getTemp is not a function in uni-app typically indicates that the method getTemp is either not defined or not accessible in the current context. Here are some common reasons and solutions for this issue:

1. Method Not Defined

  • Ensure that the getTemp method is defined in your script section.
  • Example:
    export default {
  methods: {
    getTemp() {
      // Your logic here
    }
  }
}

2. Incorrect Context

  • If you’re calling getTemp from another method or lifecycle hook, ensure you’re using this to refer to the method.
  • Example:
    export default {
  methods: {
    someMethod() {
      this.getTemp(); // Correct way to call the method
    },
    getTemp() {
      // Your logic here
    }
  }
}

3. Asynchronous Issues

  • If getTemp is being called before it’s defined (e.g., in an asynchronous context), ensure the method is available when called.
  • Example:
    export default {
  mounted() {
    setTimeout(() => {
      this.getTemp(); // Ensure getTemp is defined
    }, 1000);
  },
  methods: {
    getTemp() {
      // Your logic here
    }
  }
}

4. Typo or Case Sensitivity

  • Double-check the method name for typos or case sensitivity issues. JavaScript is case-sensitive, so getTemp and gettemp are different.

5. Using getTemp in a Non-Method Context

  • If getTemp is not a method but a function defined outside the component, ensure it’s imported or defined correctly.
  • Example:
    function getTemp() {
  // Your logic here
}

export default {
  methods: {
    someMethod() {
      getTemp(); // Call the external function
    }
  }
}
