This time I will show you how to quickly solve jQuery's request to transmit garbled Chinese parameters, and how to quickly solve jQuery's request to transmit garbled Chinese parameters. . The demand I am currently working on involves cascading
Query. It is necessary to query the list of lower-level drop-down boxes based on the content of the upper-level drop-down box, because the cascade only has two levels, and the table will be updated later. The data in will almost never change, so the table I designed stores Chinese directly. The menu is as follows:
The code is as follows:
var url = "${basePath}/institutionConfig/getDepartmentByCenter.do?param=" + center; $.get(url, function (data) { var list = data.data; for (var i = 0; i " + list[i] + ""; } $("#accountDepartmentAdd").html(departmentSelector); });
I use
$.get(url, callback) When sending a request to the background, since the parameters are sent directly in GET mode, the browser encodes the parameters with URL encoding, and the parameters obtained by the background are:
As you can see, param received garbled characters. So I performed further processing, that is, transcoding:
String center = new String(param.getBytes("iso8859-1"), "utf-8");
so that the received text is Chinese.
However, this approach actually reported an error in the test environment. After analyzing the reason, I found that the test environment received the correct Chinese, but it turned out to be wrong after transcoding. Therefore, the solution should be to change the page request. Because the parameters caused by the GET method are encoded, it is changed to
POST request. The POST request will submit the original data: var url = "${basePath}/institutionConfig/getDepartmentByCenter.do";
$.ajax({
url: url,
data: {"param": center},
dataType: "json",
type: "POST",
success: function (data) {
var list = data.data;
for (var i = 0; i " + list[i] + "";
}
$("#accountDepartmentAdd").html(departmentSelector);
}
});
I believe you have mastered the method after reading the case in this article, and more How exciting, please pay attention to other related articles on php Chinese website!

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

在jquery中,apply()方法用于改变this指向,使用另一个对象替换当前对象,是应用某一对象的一个方法,语法为“apply(thisobj,[argarray])”;参数argarray表示的是以数组的形式进行传递。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。

去掉方法:1、用“$(selector).removeAttr("readonly")”语句删除readonly属性;2、用“$(selector).attr("readonly",false)”将readonly属性的值设置为false。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
