微信小程序试水教程：富文本转文本

returnText = returnText.replace(/<\/ul>/ig, '\r\n');

//-- remove BR tags and replace them with line break

returnText = returnText.replace(//gi, "\r\n");

//-- remove P and A tags but preserve what's inside of them

returnText=returnText.replace(//gi, "\r\n");

returnText=returnText.replace(/(.*?)<\/a>/gi, " $2 ($1)");

//-- remove all inside SCRIPT and STYLE tags

returnText=returnText.replace(/[\w\W]{1,}(.*?)[\w\W]{1,}<\/script>/gi, "");

returnText=returnText.replace(/[\w\W]{1,}(.*?)[\w\W]{1,}<\/style>/gi, "");

//-- remove all else

returnText=returnText.replace(/<(?:.|\s)*?>/g, "");

//-- get rid of more than 2 multiple line breaks:

returnText=returnText.replace(/(?:(?:\r\n|\r|\n)\s*){2,}/gim, "\r\n\r\n");

//-- get rid of more than 2 spaces:

returnText = returnText.replace(/ +(?= )/g,'');

//-- get rid of html-encoded characters:

returnText=returnText.replace(/ /gi," ");

returnText=returnText.replace(/&/gi,"&");

returnText=returnText.replace(/"/gi,'"');

returnText=returnText.replace(/</gi,'<');

returnText=returnText.replace(/>/gi,'>');

return returnText;

}

将上面代码放进任一适宜的小程序js文件中， 然后在须要处置数据的js文件里，导入文件，下面得出放进app.js文件中的调用示例：

var app = getApp()//以获取app小程序实例

onLoad: function (options) {

wx.request({

url: 'http://example.com/api' + options.id+'.json',

headers: {

'Content-Type': 'application/json'

},

success: function (res) {

res.data.content = app.convertHtmlToText(res.data.content )

that.setData({

art: res.data.content

})

console.log(res.data)

}

})

｝

然后编程创下下，可以看见结果了：

这里可以稳步调整之下css，并使表明得更好看点。
