如果不满足条件,如何在不重复的情况下执行内部函数?
How to execute a function inside if without being repetitive if the condition is not met?
这是中继突变的代码,我必须重新加载,这样存储才能与数据库同步,因为出于某种原因,如果文本与之前添加的文本相同,中继存储会抛出错误 flattenChildren.. .
_handleTextInputSave = (text) => {
if(checkIfTextAlreadyExists(text) && window.confirm("Todo already exists! Please confirm to proceed.")) {
AddTodoMutation.commit(
this.props.relay.environment,
text,
this.props.viewer,
);
location.reload();
}
AddTodoMutation.commit(
this.props.relay.environment,
text,
this.props.viewer,
);
};
我想不出其他方法,因为如果文本已经存在,我必须重新加载,但不知怎的,我觉得 AddTodoMutation.commit 是多余的。你怎么看?我将不胜感激。
看起来你总是想提交并且只在有条件的情况下重新加载。所以写:
_handleTextInputSave = (text) => {
const exists = checkIfTextAlreadyExists(text) && window.confirm("Todo already exists! Please confirm to proceed.");
AddTodoMutation.commit(
this.props.relay.environment,
text,
this.props.viewer,
);
if (exists)
location.reload();
};
