Question

我有一个函数，如果达到特定宽度，我必须只运行一次。

函数用于仅在移动

上转置表（包含行的列）

我需要什么：

1. ON LOAD
a. if width <992 run transposeTable (mobiles)
b. if width> 992 do nothing

2. ON RESIZE
a. if width <992 run transposeTable ONLY ONCE BUT if loaded page has a smaller width than 992px do nothing (see 1)
b. if width> 992 run transponseTable ONLY ONCE BUT if loaded page has a width greater than 992px to nothing (see 1)

这里的解决方案（有一些修改）感谢@Olaf Nankman

var transposed = "desktop";
$(document).ready(function(){
    if($(window).width() < 992){
        transposed = "mobile"
        transposeTable();
    }else{
        transposed = "desktop"
    }
})
$(window).resize(function(){
    if($(window).width() < 992 && transposed != "mobile"){
        transposed = "mobile"
        transposeTable();
    }

    if($(window).width() > 992 && transposed != "desktop"){
        transposed = "desktop"
        transposeTable();
    }
})

您必须存储已经调用from matplotlib import pyplot as plt from matplotlib import pylab as pl pl.plot(matrix[:,0],matrix[:,1], 'ro')函数的内容，并且应该使用其他函数将表转置到桌面... 例如：

transposeTable

如果这有用，可以满足我的需求

var x;
$(window).resize(function() {
  if ($(this).width() <= 600 && (x === 2 || x === undefined)) {
    if(x !== undefined){
      //function here
      $("body").append('size: small<br/>');
    }
    x = 1;
  }
  else if ($(this).width() > 600 && $(this).width() <= 1140 && (x === 1 || x === 3 || x === undefined)){
    if(x !== undefined){
      //function here
      $("body").append('size: medium<br/>');
    }
    x = 2;
  }
  else if ($(this).width() > 1140 && (x === 2 || x === undefined)){
    if(x !== undefined){
      //function here
      $("body").append('size: large<br/>');
    }
    x = 3;
  }
});

jQuery Run函数只在窗口大小调整一次
