我有以下javascript。
问题是,如果我在表“components”中输入一行,但是在我的C#对象中,我在得到的传递给控制器操作时得到2行。但第二个对象是null?
我检查了javascript,变量“cnt”是1而不是2。
为什么会这样?

$("#Save").click(function () {
var title = $("#recipetitle").val();
var category = $("#category").val();
var preptime = $("#prepTime").val();
var preptimeperiod = $("#lstPrepTime").val();
var cooktime = $("#cookTime").val();
var cooktimeperiod = $("#lstCookTime").val();
var rating = $("#rating").val();
var method = $("#method").val();
var jsontext = '{ "RecipeTitle": "' + title + '",';
jsontext += '"CategoryID":' + category + ',';
jsontext += '"PrepTime":' + preptime + ',';
jsontext += '"PrepTimePeriod":"' + preptimeperiod + '",';
jsontext += '"CookTime":' + cooktime + ',';
jsontext += '"CookTimePeriod":"' + cooktimeperiod + '",';
jsontext += '"Rating":' + rating + ',';
jsontext += '"Method":"' + method + '",';
var ing = "";
var cnt = 0;
$("#ingredients tr.ingredientdata").each(function () {
if ($("td.ingredient", this).text() != "") {
ing += '{ "IngredientName": "' + $("td.ingredient", this).text() + '",';
ing += '"Units": ' + $("td.units", this).text() + ',';
ing += '"Measure": "' + $("td.measure", this).text() + '"} ,';
}
cnt = cnt + 1;
});
alert(cnt);
if (ing != "") {
jsontext += '"Ingredients": [';
ing = ing.substring(0, jsontext.length - 1);
jsontext = jsontext + ing;
jsontext += ']';
}
jsontext += '}';
var json = eval('(' + jsontext + ')');
//var json = { Field: 1 };
$.ajax({
url: "/Recipe/Save",
type: "POST",
dataType: 'json',
data: JSON.stringify(json),
contentType: "application/json; charset=utf-8",
success: function () {
//alert("DONE!!");
}
});
}); [/代码]

我建议您重构一下javascript,因为它可以帮助您更轻松地识别错误。还可以使用FireBug检出发送给控制器的实际JSON请求:
$("#Save").click(function () {
var ingredients = $('#ingredients tr.ingredientdata').map(function(index, element) {
return {
ingredientName: $('td.ingredient', element).text(),
units: $('td.units', element).text(),
measure: $('td.measure', element).text()
};
});
var json = {
RecipeTitle: $('#recipetitle').val(),
CategoryID: $('#category').val(),
PrepTime: $('#prepTime').val(),
PrepTimePeriod: $('#lstPrepTime').val(),
CookTime: $('#cookTime').val(),
CookTimePeriod: $('#lstCookTime').val(),
Rating: $('#rating').val(),
Method: $('#method').val(),
Ingredients: ingredients
};
$.ajax({
url: '/Recipe/Save',
type: 'POST',
dataType: 'json',
data: JSON.stringify(json),
contentType: 'application/json; charset=utf-8',
success: function () {
//alert("DONE!!");
}
});
});
