javascript - 如何最小化JavaScript中的if语句

我有很长的if-condition语句。如何最小化？
这是我的代码，

if(this.refs.category.value.trim() != "" &&
        this.refs.decisive_min.value.trim() != "" && this.refs.decisive_max.value.trim() != "" &&
        this.refs.interactive_min.value.trim() != "" && this.refs.interactive_max.value.trim() != "" &&
        this.refs.stabilizing_min.value.trim() != "" && this.refs.stabilizing_max.value.trim() != "" &&
        this.refs.cautious_min.value.trim() != "" && this.refs.cautious_max.value.trim() != "" &&
        this.refs.aesthetic_min.value.trim() != "" && this.refs.aesthetic_max.value.trim() != "" &&
        this.refs.economic_min.value.trim() != "" && this.refs.economic_max.value.trim() != "" &&
        this.refs.individualistic_min.value.trim() != "" && this.refs.individualistic_max.value.trim() != "" &&
        this.refs.political_min.value.trim() != "" && this.refs.political_max.value.trim() != "" &&
        this.refs.altruist_min.value.trim() != "" && this.refs.altruist_max.value.trim() != "" &&
        this.refs.regulatory_min.value.trim() != "" && this.refs.regulatory_max.value.trim() != "" &&
        this.refs.theoretical_min.value.trim() != "" && this.refs.theoretical_max.value.trim() != ""){
        var data = {category:this.refs.category.value.trim()};
        data.decisive_min = this.refs.decisive_min.value.trim();
        data.decisive_max = this.refs.decisive_max.value.trim();
        data.interactive_min = this.refs.interactive_min.value.trim();
        data.interactive_max = this.refs.interactive_max.value.trim();
        data.stabilizing_min = this.refs.stabilizing_min.value.trim();
        data.stabilizing_max = this.refs.stabilizing_max.value.trim();
        data.cautious_min = this.refs.cautious_min.value.trim();
        data.cautious_max = this.refs.cautious_max.value.trim();
        data.aesthetic_min = this.refs.aesthetic_min.value.trim();
        data.aesthetic_max = this.refs.aesthetic_max.value.trim();
        data.economic_min = this.refs.economic_min.value.trim();
        data.economic_max = this.refs.economic_max.value.trim();
        data.individualistic_max = this.refs.individualistic_max.value.trim();
        data.individualistic_min = this.refs.individualistic_min.value.trim();
        data.political_min = this.refs.political_min.value.trim();
        data.political_max = this.refs.political_max.value.trim();
        data.altruist_min = this.refs.altruist_min.value.trim();
        data.altruist_max = this.refs.altruist_max.value.trim();
        data.regulatory_min = this.refs.regulatory_min.value.trim();
        data.regulatory_max = this.refs.regulatory_max.value.trim();
        data.theoretical_min = this.refs.theoretical_min.value.trim();
        data.theoretical_max = this.refs.theoretical_max.value.trim();

我只想检查表单中的所有值，如果它们都不是空字符串。

我在Meteor中使用了React JS的引用。

最佳答案

您可以使用带有所需键的数组。然后只需要分配和检查一个循环。

如果所有值均为真，则data包含修剪后的值，否则为undefined。

var keys = ['category', 'decisive_min', 'decisive_max', 'interactive_min', 'interactive_max', 'stabilizing_min', 'stabilizing_max', 'cautious_min', 'cautious_max', 'aesthetic_min', 'aesthetic_max', 'economic_min', 'economic_max', 'individualistic_min', 'individualistic_max', 'political_min', 'political_max', 'altruist_min', 'altruist_max', 'regulatory_min', 'regulatory_max', 'theoretical_min', 'theoretical_max'],
    data = {};

data = keys.every(function (k) {
    return data[k] = this.refs[k].value.trim();
}, this) && data || undefined;
