问题描述
我对管理目的的Web表单，用户可以更改顺序的一组记录在网页上显示。
例如：在数据库中的表（tblStuff）有三个领域：
内容识别，内容，RecordPosition
该表格，说，四个记录：
1，你猜怎么着，1
2，更多的东西，2
3，有些东西，3
4，这是正确的，4
在SQL code是：
SELECT * FROM tblStuff ORDER BY RecordPosition ASC
用户可以使用的形式来改变RecordPosition号码，这样的顺序可以阅读：
3，有些东西，1
2，更多的东西，2
1，你猜怎么着，3
4，这是正确的，4
所以...我如何可以验证的形式，使同样数量的未输入两次踏入RecordPosition领域？
希望这是有道理的。

解决方案
让我们假设你有表所示（请注意所有的输入具有相同的类）：
＆LT;表ID =myForm会的方法=POST行动someUrl＆GT;
＆LT;输入类型=文本级=recordPosition＆GT;＆LT; /输入＆GT;
＆LT;输入类型=文本级=recordPosition＆GT;＆LT; /输入＆GT;
＆LT;输入类型=文本级=recordPosition＆GT;＆LT; /输入＆GT;
＆LT;输入类型=文本级=recordPosition＆GT;＆LT; /输入＆GT;
＆LT; /表及GT;
您可以用jQuery像这样做的：
$（文件）。就绪（函数（）{ $（。recordPosition）。在（模糊，函数（）{
VAR allFieldsForOrder = $（'。recordPosition'）;
变种数= 0;
变种I = 0
//console.log(allFieldsForOrder.length）;
而（（ⅰ＆下; allFieldsForOrder.length）及及（计数2））{
如果（$（allFieldsForOrder [I]）。VAL（）=== $（本）.VAL（））
{
算上++
}
我++;
} 如果（计数== 2）{
警报（A重复值）;返回false;}
}）;
}）;
有关你贴，你可以使用这个HTML：
的通知我不存储重复值的位置。
$（文件）。就绪（函数（）{
//console.log($(\"input[type='text'][name^='PositionNumber'\").length）;
$（输入[类型=文本] [^名字='PositionNumber'）。每个（函数（）{
$（本）。在（模糊，函数（）{ VAR allFieldsForOrder = $（输入[类型=文本] [^名字='PositionNumber'）;
变种数= 0;
变种I = 0 而（（ⅰ＆下; allFieldsForOrder.length）及及（计数2））{
如果（$（allFieldsForOrder [I]）。VAL（）=== $（本）.VAL（））
{
算上++
}
我++;
} 如果（计数== 2）{
警报（A重复值）;
} }）;
}）;
}）;
为code以上，我们假设您要检查所有字段其中属性名以字符串PositionNumber启动
我稍后会尝试减少code，我觉得有来检查是否复制了RecordPosition的价值，但需要测试的一些想法的最短途径。
这将是您的解决方案（其中之一）：
$（文件）。就绪（函数（）{
$（'形式'）。在（提交，函数（）{
变种tempArray = [];
$（输入[类型=文本] [^名字='PositionNumber'）。每个（函数（）{
tempArray.push（$（本）.VAL（））;
}）; 变种I = 0;
VAR重复= FALSE;
VAR currentElement;
而（（tempArray.length＆GT = 0）及及（重复==假））{
//从数组中弹出出来
currentElement = tempArray.pop（）;
复制= tempArray.indexOf（currentElement） } //后，可以使用复制，以取消提交
如果（重复）{
警报（重复值：+ currentElement）;
返回false;
} }）;
}）;
我较短的版本：
$（文件）。就绪（函数（）{
$（'形式'）。在（提交，函数（）{
变种tempArray = [];
变种存在= 0;
$（输入[类型=文本] [^名字='PositionNumber'）。每个（函数（）{
存在= tempArray.indexOf（$（本）.VAL（））;
如果（存在＆GT; = 0）{
返回false; //打破循环
}
tempArray.push（$（本）.VAL（））;
}）; //以后可以用存在，以检查是否复制和检索值，以取消提交
如果（存在＆GT; = 0）{
警报（重复值：+ tempArray [存在]）;
}其他{
警报（没有重复值：）;
} 返回false;
}）;
}）;
I have a web form for admin purposes where the user can change the order that a group of records is shown on a webpage.
For example: A table (tblStuff) in a database has three fields:
ContentID, Content, RecordPosition
The table has, say, four records:
1, Guess what, 1
2, More stuff, 2
3, Some stuff, 3
4, That's right, 4
The SQL code is:
SELECT * FROM tblStuff ORDER BY RecordPosition ASC
The user can use the form to change the RecordPosition number so that the order can read:
3, Some stuff, 1
2, More stuff, 2
1, Guess what, 3
4, That's right, 4
So... How can I validate the form so that the same number isn't entered twice into the RecordPosition field?
Hope this makes sense.
Here's the whole page

解决方案
Let's suppose you have form like this (notice all the inputs has the same class):
<form id="myForm" method="POST" action"someUrl">
<input type="text" class="recordPosition"></input>
<input type="text" class="recordPosition"></input>
<input type="text" class="recordPosition"></input>
<input type="text" class="recordPosition"></input>
</form>
You could do with jQuery something like this:
$(document).ready(function(){
$(".recordPosition").on("blur", function(){
var allFieldsForOrder = $('.recordPosition');
var count = 0;
var i=0
//console.log(allFieldsForOrder.length );
while((i<allFieldsForOrder.length) && (count < 2)){
if ($(allFieldsForOrder[i]).val()===$(this).val())
{
count++
}
i++;
}
if (count==2){
alert("A duplicated value"); return false;}
});
});
For the html you posted you can use this: Notice I don't store the position of the duplicated the value.
$(document).ready(function(){
//console.log($("input[type='text'][name^='PositionNumber'").length);
$("input[type='text'][name^='PositionNumber'").each(function(){
$(this).on("blur", function(){
var allFieldsForOrder = $("input[type='text'][name^='PositionNumber'");
var count = 0;
var i=0
while((i<allFieldsForOrder.length) && (count < 2)){
if ($(allFieldsForOrder[i]).val()===$(this).val())
{
count++
}
i++;
}
if (count==2){
alert("A duplicated value");
}
});
});
});
For the code above we assume you want to check for all the fields where the attribute name starts with the string "PositionNumber"
I will try to reduce the code later, I think there's a shortest way to check if is duplicated the "RecordPosition" value, but need to test some ideas.
This will be your solution (one of them):
$(document).ready(function(){
$('form').on("submit",function(){
var tempArray=[];
$("input[type='text'][name^='PositionNumber'").each(function(){
tempArray.push($(this).val());
});
var i=0;
var duplicated=false;
var currentElement;
while((tempArray.length >= 0) && (duplicated==false)){
//pop it out from the array
currentElement = tempArray.pop();
duplicated = tempArray.indexOf(currentElement)
}
//after you can use "duplicated" to cancel the submit
if (duplicated){
alert("duplicated value:" + currentElement);
return false;
}
});
});
I shorter version:
$(document).ready(function(){
$('form').on("submit",function(){
var tempArray=[];
var exists=0;
$("input[type='text'][name^='PositionNumber'").each(function(){
exists = tempArray.indexOf($(this).val());
if (exists>=0){
return false;//break the loop
}
tempArray.push($(this).val());
});
//after you can use "exist" to check if duplicated and retrieve the value to cancel the submit
if (exists>=0){
alert("duplicated value:" + tempArray[exists]);
} else{
alert("no duplicated value:");
}
return false;
});
});
