1)我总共有三个文本框,我有一个REST API,它可以获取所有数据 我想搜索匹配的记录
2)如果用户输入开始日期,我们应该获得所有与文本匹配的开始日期匹配记录
3)我有3个文本字段,我想获取仅与所有三个文本字段(开始日期,id和标题通用的方式)匹配的数据
4)我已经完成或满足条件,但是我不知道如何匹配3步的要求,请帮助我我同时需要2和3的功能
答案 0 :(得分:0)
如果您已经完成了条件
if (a ==obj[i]["ProductID"] || b==obj[i]["Title"] || c==obj[i]["startDate"] ){
console.log(a);
console.log(b);
}
此条件。然后要求3,因为所有三个匹配都是
if (a ==obj[i]["ProductID"] && b==obj[i]["Title"] && c==obj[i]["startDate"] ){
console.log(a);
console.log(b);
}
这仅在所有三个文本字段都匹配时才返回true。
我会将您的for循环更改为
var a= $( "#100" ).val();
var b= $( "#101" ).val(); // There is no need to recreate these variables every time. once is enough.
var c = $( "#102" ).val();
for(var i=0;i<obj.length;i++){
if (a ==obj[i]["ProductID"] && b==obj[i]["Title"] && c==obj[i]["startDate"] ){
console.log(a);
console.log(b);
console.log(C);
}
else if (a ==obj[i]["ProductID"] || b==obj[i]["Title"] || c==obj[i]["startDate"]){
console.log(a);
console.log(b);
}
关于要求2,类似
if (c==obj[i]["startDate"] ){
console.log(a);
console.log(b);
console.log(C);
}
将为您提供与开始日期匹配的每个元素的所有记录,从而使您的for循环看起来像
var a= $( "#100" ).val();
var b= $( "#101" ).val(); // There is no need to recreate these variables every time. once is enough.
var c = $( "#102" ).val();
for(var i=0;i<obj.length;i++){
if (c==obj[i]["startDate"] ){
console.log(a);
console.log(b);
console.log(C);
}
if (a ==obj[i]["ProductID"] && b==obj[i]["Title"] && c==obj[i]["startDate"] ){
console.log(a);
console.log(b);
console.log(C);
}
else if (a ==obj[i]["ProductID"] || b==obj[i]["Title"] || c==obj[i]["startDate"]){
console.log(a);
console.log(b);
}
}
至于页面底部。我会改变
}) // Missing semicolon
}
</script>
</body>
</form> <!-- Needs to be closed inside of the body tag -->
</html>
对此:
});
}
</script>
</form>
</body>
</html>
我不确定为什么在表单中有表单,但是没关系....上面的以下代码应该可以帮助您进行测试。如果我误解了您的问题,请随时进行澄清。
